CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This nonprovisional application claims priority under 35
U.S.C. .sctn.119(a) on Patent Application Nos. 2003-399041 and
2004-307840 filed in Japan on Nov. 28, 2003 and Oct. 22, 2004,
respectively, the entire contents of which are hereby incorporated
by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] This invention relates to a printing system for printing
print information on a print-information recording medium and for
writing electronic information into an electronic-information
recording medium carried on the print-information recording medium,
and more particularly, to a printing system capable of writing
electronic information into an electronic-information recording
medium in a manner consistent with print information including at
least either one of contactlessly readable code information and
image information visible to human being.
[0004] 2. Description of the Related Art
[0005] Instead of a conventional information recording medium such
as a magnetic card and a contact-type IC card, an information
recording medium (hereinafter referred to as RFID tag) has been
developed, which is comprised of a print-information recording
medium and an electronic-information recording medium (hereinafter
referred to as RFID chip) such as IC chip, and in which the
electronic-information recording medium is carried on the
print-information recording medium and is adapted to allow
electronic information to be contactlessly read therefrom and
written thereto. Thus, the RFID tag can eliminate the necessity of
being kept in contact with a readout/write device at the time of
electronic information being read from and written into the RFID
tag, and therefore, the RFID tag is especially expected as
alternative to a bar code that is used in distribution management
(see for example, Japanese unexamined patent publication no.
11-353435).
[0006] The bar code conventionally used for distribution management
is adapted to be read by use of a special-purpose device, and
therefore, the bar code content cannot generally immediately be
recognized by human being by glancing at the bar code. In this
regard, image information (character information and/or symbolic
information) which is visible to and whose content is
understandable to human being (hereinafter referred to as "image
information visible to human being") is sometimes printed at the
same time when the bar code is printed.
[0007] The printing of bar code and the printing of image
information visible to human being can be made by using the same
printing system, and hence it is relatively easy to ensure the
consistency between information given by a bar code and image
information visible to human being. On the other hand, the writing
of electronic information (hereinafter referred to as RFID data)
into the RFID chip is performed by use of a device different from a
device for printing image information visible to human being.
Moreover, according to the prior art, in most cases, different
applications are used for preparation, edition, and management of
print data of image information visible to human being and of RFID
data written into the RFID tag. This makes it difficult to ensure
the consistency between the RFID data (electronic information) to
be written into the RFID tag and the image information printed
thereon.
[0008] To print the image information visible to human being onto
the print-information recording medium of the RFID tag, a laser
printer or the like is ordinarily used. A mainstream laser printer
or the like employs a high temperature roller that is adapted to be
in contact with the print-information recording medium in order to
fix toner to the recording medium. Due to the presence of the high
temperature roller, there is a fear that the RFID tag can be
damaged.
[0009] In an existing printer engine or the like that is used to
print the image information visible to human being, the
print-information recording medium is often bent therein.
Therefore, the RFID tag, especially the RFID chip carried on the
print-information recording medium, can be damaged due to the
bending of the recording medium.
SUMMARY OF THE INVENTION
[0010] The object of this invention to provide a printing system
that is capable of writing RFID data (electronic information)
consistent with print information printed on a print-information
recoding medium into a RFID chip (electronic-information recording
medium) carried on the print-information recording medium.
[0011] A printing system of this invention comprises a printer
engine for printing print information on at least a
print-information recording medium, said print information
including at least either one of contactlessly readable information
and image information visible to human being, and an RFID
reader/writer for writing RFID data consistent with the print
information into an RFID chip carried on the print-information
recording medium.
[0012] According to the printing system of this invention, an RFID
tag can be prepared, without causing inconsistency between print
information printed on the print-information recording medium (or
printed on both the print-information recording medium and the RFID
chip carried thereon) and the RFID data (electronic information)
written into the RFID chip.
[0013] The printing system of this invention may further comprise
optical readout means for contactlessly reading the code
information. In this preferred embodiment, the printer engine
prints at least the code information on at least the
print-information recording medium, and the RFID reader/writer
writes the RFID data into the RFID chip based on the code
information read by the optical readout means. According to this
preferred embodiment, the RFID data consistent with the code
information printed on the print-information recording medium can
be written into the RFID chip.
[0014] In another preferred embodiment, the RFID reader/writer
reads the RFID data written into the RFID chip, and the printer
engine prints the print information on at least the
print-information recording medium based on the RFID data read by
the RFID reader/writer. According to this preferred embodiment, the
print information consistent with the RFID data written into the
RFID chip can be printed on the print-information recording
medium.
[0015] Preferably, the printer engine prints the code information
and the image information consistent therewith on at least the
print-information recording medium. In this case, both the code
information and the image information are printed, serving as print
information, onto at least the print-information recording medium.
More preferably, the printer engine prints a bar code on at least
the print-information recording medium, said bar code providing
information that constitutes at least part of the code information.
In this case, the bar code is printed as the code information on
the print-information recording medium.
[0016] Preferably, the printing system comprises a plurality of
RFID readers/writers, and these RFID readers/writers write the RFID
data into the RFID chip. According to this preferred embodiment,
the RFID chip may have a storage region that is divided into a
plurality of areas, so that each area may be written with a
corresponding part of the RFID data by means of a corresponding one
of the plurality of the RFID readers/writers. This makes it
possible to write the RFID data into the RFID chip with
reliability, even if the printing system is high in printing
speed.
[0017] Alternatively, the printing system may comprise a plurality
of RFID readers/writers and a plurality of RFID chips. Each of the
RFID readers/writers writes the RFID data into a corresponding one
of the plurality of RFID chips, and the plurality of RFID
readers/writers perform writings nearly simultaneously. According
to this preferred embodiment, the writing of the RFID data into the
RFID chips can be efficiently and reliably performed by means of
the RFID readers/writers.
[0018] The printing system of this invention may further comprise a
printer controller for supplying print data. In this preferred
embodiment, the printer engine prints the print information on at
least the print-information recording medium based on the print
data received from the printer controller, and the RFID
reader/writer writes the RFID data consistent with the print data
into the RFID chip. According to this preferred embodiment, the
print information and the RFID data are each consistent with the
print data, whereby not only the print information and the RFID
data can be made consistent with each other, but also both the
printing of the printing information and the writing of the RFID
data can be carried out by means of a single printing system.
[0019] Preferably, the printing of the print information on at
least the print-information recording medium based on the print
data and the writing of the RFID data consistent with the print
data into the RFID chip are controlled based on a common time
basis. More preferably, the printer engine performs page-based
printing, and the common time basis is based on a cycle of the
page-based printing of the printer engine. According to this
preferred embodiment, it is possible to make the print information
and the RFID data consistent with each other with reliability.
[0020] Preferably, the printing system of this invention further
comprises a form layout application program capable of editing both
the print data and the RFID data. In this case, not only the
editing of the print data and the RFID data can be efficiently
carried out, but also the data editing as well as both the printing
and the RFID data writing based on the edited data can be carried
out by means of a single printing system. This is efficient. More
preferably, at least part of the RFID data is transmitted in the
form of PDL (page description language) data from the form layout
application program to the printer controller.
[0021] It is preferable that the printer controller or the form
layout application program is capable of recording or displaying
information that indicates whether or not the RFID reader/writer
can write the RFID data into the RFID chip, and it is also
preferable that the form layout application program is capable of
specifying error processing in the printer controller. According to
this preferred embodiment, the data writing can reliably be carried
out, with the RFID reader/writer ready for data writing. When there
occurs an error, an appropriate countermeasure such as printing
stoppage can be made and an operator can be notified of the
occurrence of error.
[0022] It is preferable that the printer controller or the form
layout application program is capable of displaying an edit screen
for the print data, and that the RFID data can be displayed on the
edit screen. This preferred embodiment makes it easy for an
operator to perform data editing.
[0023] Preferably, the form layout application program can specify
position information on a location of the RFID data in one page of
the print-information recording medium. With this preferred
embodiment, it is possible to appropriately perform the writing of
the RFID data into the RFID chip that is carried on the
print-information recording medium at an arbitrary position.
[0024] Preferably, the printer system is capable of referring to a
database, and a database address serving as at least either one of
the print data and the RFID data can be edited in the form layout
application program. According to this preferred embodiment, an
amount of data transmitted from the form layout application program
to the printer controller can be reduced, and the RFID data can be
altered by altering the content of the database.
[0025] In the printing system, a plurality of RFID readers/writers
may be provided so as to be juxtaposed in a width direction of the
print-information recording medium, and a plurality of RFID chips
may be carried on the print-information recording medium so as to
be juxtaposed in a width direction of the print-information
recording medium. Each of the RFID readers/writers writes the RFID
data into a corresponding one of the RFID chips, and the RFID
readers/writers perform the writings nearly simultaneously.
According to this preferred embodiment, the writing of the RFID
data into the RFID chips can be made appropriately and
efficiently.
[0026] In the printing system, a plurality of RFID chips may be
carried on one page of the print-information recording medium as
viewed in a direction of transfer of the recording medium. The RFID
reader/writer sequentially writes the RFID data into each of the
RFID chips. With this preferred embodiment, the writing of the RFID
data into the RFID chips can be made with use of a single RFID
reader/writer.
[0027] It is preferable that a printing speed of the printer engine
can be changed in accordance with an amount of information of the
RFID data. With this preferred embodiment, the consistency between
print information and RFID data can be ensured without regard to
the printing speed.
[0028] In the printing system, a print face of the
print-information recording medium on which the print information
is printed may have a level difference, and the print information
may be printed on a substantially flat portion of the print face,
avoiding the level difference. With this preferred embodiment, the
print information can be printed appropriately, even if the print
face has such a level difference.
[0029] The printing system of this invention may further comprise
fixing means disposed out of contact with the print-information
recoding medium carrying the RFID chip, transfer means for
substantially linearly transferring the print-information recording
medium carrying the RFID chip, and cooling means for cooling at
least either one of the print-information recording medium carrying
the RFID chip and the transfer means. In this preferred embodiment,
the RFID tag (the print-information recording medium on which the
RFID chip is carried) is transferred substantially linearly, and
thus the RFID tag is not bent, making it possible to prevent the
RFID tag, especially, the RFID chip from being damaged.
Furthermore, since the print-information recording medium or the
transfer means is cooled, the temperature of the RFID tag,
especially, the temperature of the RFID chip, can be suppressed
from being raised, making it possible to prevent the RFID chip from
being damaged. Preferably, the printer engine is electrographic
type, and the fixing means is flash fixing type. By adopting the
fixing means of flash-fixing type, a temperature rise in the RFID
tag can be suppressed, and the RFID chip can be prevented from
being damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0050] With reference to FIGS. 1-7, a printing system according to
a first embodiment of this invention will be explained. This
printing system is suitable for preparation of packing slips for
home delivery service that are used at the time of delivery of
goods in large quantity from a department store or a mail-order
selling company.
[0051] FIGS. 1 and 2 are a block diagram and a schematic structural
view of the printing system, respectively. In this printing system,
an electrographic printer engine is adopted as shown in FIG. 2.
FIG. 3 shows an example of an RFID tag 11 used in the printing
system, and FIGS. 6 and 7 show another example of the RFID tag 11.
As shown in FIG. 7, the RFID tag 11 comprises a print-information
recording medium 24 (hereinafter sometimes referred to as print
medium) on which an RFID chip 25 is carried.
[0052] Meanwhile, although the RFID chip 25 is carried on the
print-information recording medium 24, and the recording medium 24
per se constitutes the RFID tag 11 in this embodiment, there may be
an arrangement where the RFID tag 11 is held on another medium (for
example, the RFID tag 11 having a rear face thereof applied with
adhesive glue is held on a medium that is comprised of a mount such
as a separating paper).
[0053] FIG. 4 shows part of an example of a database 31 used in
this printing system. In the database 31, pieces of data relating
to goods to be delivered are stored for every goods in the form of
data records. Each data record is constituted by a data record
number (data ID), addressee information, client information,
distribution information, and goods information. The addressee
information and the client information each include zip code,
address, name, telephone number, etc. The distribution information
includes a shipping store code identifying a shipment point, an
arrival store code identifying an arrival point, an inquiry number
used by a customer to trace the status of delivery of goods. The
goods information includes information on weight and size of goods,
indication of fragile content, etc.
[0054] From the database 31, a printer controller 22 reads various
pieces of information in the data record to be processed, and
produces image information (character information and/or symbolic
information, for instance) that is visible to human being. At the
same time, from information such as the data record number (data
ID) contained in the data record to be processed, the printer
controller 22 produces image information that is readable by
optical reading means (hereinafter sometimes referred to as code
information). As shown in FIG. 2, these pieces of image information
are transferred onto the RFID tag 11 (for instance, onto a surface
of the print medium 24 of the tag 11) by means of a printer engine
1 (shown by reference numeral 1 in FIG. 1). Hereinafter, the image
information visible to human being and the optically readable image
information will collectively be referred to as print information.
More specifically, in the printer engine 1, a latent image is
formed on latent-image carrying means 8 by latent-image formation
means 7, is developed by developing means 9, and is transferred to
the RFID tag 11 by transfer means 10.
[0055] FIG. 3 shows an example of pieces of image information
formed on the RFID tag 11 by the image transfer. In FIG. 3,
reference numerals 17, 18, and 19 denote pieces of image
information produced from addressee information, from client
information, and from distribution information, respectively. For
the production of image information, it is unnecessary to read out
all the pieces of information from the database 31. For example, in
this embodiment, the goods information is not formed into image
information. Reference numeral 20 denotes image information of a
code (code information) that is readable by optical reading means.
The code information of this embodiment is given in the form of
one-dimensional bar code, but may be a two-dimensional bar code, or
characters which can be recognized by optical character recognition
(OCR).
[0056] As shown in FIG. 2, the RFID tag 11 onto which the image
information has already been transferred is transported in the
printing system. At this time, if the RFID tag 11 is largely bent
at the printer engine 1, an RFID chip 25 carried on the RFID tag
may sometimes be damaged. To obviate this, the printer engine 1 of
this embodiment is arranged such that the RFID tag 11 is
transferred nearly linearly by the transportation means 12, without
being bent or curved.
[0057] With the progress of transportation of the RFID tag 11, the
image information formed on the RFID tag 11 as previously explained
is fixed by non-contact fixing means 13 of the printer engine 1.
The non-contact fixing means 13 is based on a flash fixing method,
in which the RFID tag 11 is kept out of contact with a
high-temperature roll of the fixing section, thus preventing the
RFID chip 25 carried on the RFID tag 11 from being damaged.
[0058] In this embodiment, the printer engine 1 is provided with
cooling means 14a for cooling the transporting means 12 and cooling
means 14b for directly cooling the RFID tag 11, so as to keep the
transporting means 12 and the RFID tag 11 at temperatures equal to
or below a heat-resistance temperature of the RFID chip 25. The
cooling means 14a, 14b may be of air-cooled type using fan or the
like, or may be of water-cooled type using refrigerant.
[0059] The reason why the cooling means 14a, 14b are provided is
that the temperature of the transporting means 12 can exceed the
heat-resistance temperature of the RFID chip 25 due to the presence
of energy irradiated from the flash lamp although the temperature
of the RFID tag 11 per se hardly increases when the flash fixing is
adopted. If the temperature of the transporting means 12 increases,
the temperature of the RFID tag 11 can also exceed the
heat-resistance temperature of the RFID chip 25, sometimes
resulting in the RFID chip 25 being damaged. In some cases, it is
necessary to provide means for suppressing the temperatures of the
transporting means 12 and the RFID tag 11 to below or equal to the
heat-resistance temperature of the RFID chip 25.
[0060] The printer engine 1 of this invention may be arranged to
have either one or more of the following: the transporting means 12
for nearly linearly transporting the RFID tag 11, the non-contact
fixing means 13, and the cooling means 14a, 14b.
[0061] Next, as shown in FIG. 2, the RFID tag 11 is transported to
a bar code reader 15 serving as the optical reading means. The bar
code reader 15 corresponds to an optical code-reading unit 6 shown
in FIG. 1.
[0062] In FIG. 1, the code information (for instance, data ID) read
by the optical code-reading unit 6 is sent to an RFID write-data
generating subsystem 23. In accordance with the code information,
the RFID write-data generating subsystem 23 reads out the relevant
addressee information, client information, distribution
information, and goods information from the associated data record
in the database 31, and generates electronic information (RFID
data) to be written into the RFID tag 11 (more specifically, into
the RFID chip 25 of the tag 11). The data is sent to an RFID
writing unit 59, and written into the RFID tag 11. The RFID writing
unit 59 is an RFID reader/writer shown by reference numeral 5 in
FIG. 2. The RFID write-data generating subsystem 23 may be built
into the RFID writing unit 59 (RFID reader/writer 5).
[0063] In this manner, the writing of the electronic information
into the RFID tag 11 is performed by using the code information
printed on the RFID tag 11 as key, whereby the consistency is
ensured between the electronic information (RFID data) held in the
RFID tag 11 and the image information printed on the RFID tag 11
and visible to human being. The consistency can be further ensured
by disposing the bar code reader 15 and the RFID reader/writer 6 as
closest as possible to each other, as shown in FIG. 2.
[0064] In order to reliably write the RFID data into the RFID tag
11, the RFID tag 11 must be kept within an readable/writable area
of the RFID reader/writer 5 for a certain period of time. In the
case of the printer engine that is high in printing speed, the RFID
tag 11 can pass through the readable/writable area of the RFID
reader/writer 5 in a time period shorter than the time period
required for the writing processing, so that the writing of
information into the RFID tag 11 cannot be completed.
[0065] In this regard, there is some RFID tag 11 having the RFID
chip 25 whose storage region is divided into plural pages. In that
case, the RFID data is written into the RFID chip 25 in units of
page. By decreasing the number of pages into which the writing is
made by one RFID reader/writer, an amount of data to be written by
one RFID reader/writer into the RFID chip 25 decreases, and a time
period required for the writing is shortened. Therefore, especially
in the case of using a printer engine that is high in printing
speed, a plurality of, for example, two RFID readers/writers are
juxtaposed in the direction of transfer of the RFID tag 11, as
shown in FIG. 5. For example, a first RFID reader/writer 53 is
adapted to write part of the RFID data into the first page of the
RFID chip 25 and a second RFID reader/writer 54 is adapted to write
the remaining of the RFID data into the second page of the RFID
chip 25.
[0066] By doing so, even in the printer engine that is high in
printing speed, each RFID reader/writer 53 or 54 can complete the
writing processing before the RFID tag 11 passes through the
readable/writable area thereof. The number of RFID readers/writers
may be increased for a printer engine that is much higher in
printing speed.
[0067] When RFID tags 11 are carried at a shorter distance from one
another, more than one RFID tags can simultaneously be present
within the same readable/writable area, so that the same
information may be written into these RFID tags. To obviate this,
the readable/writable area of each RFID reader/writer 5 and the
distance between the RFID tags 11 must be set in such a manner that
only a single RFID tag 11 is present within the readable/writable
area of the RFID reader/writer 5.
[0068] FIG. 6 shows the RFID tag 11 used in this embodiment that
comprises the print medium 24 on which the RFID chip 25 is carried.
FIG. 7 is a sectional view taken along line A-A of FIG. 6 and
showing an RFID-chip carrying portion of the RFID tag 11.
[0069] When the RFID chip 25 has a thickness that is innegligible
compared to the thickness of the print medium 24, there is a level
difference in a print face of the print medium 24 as shown in FIG.
7. When the printing is made by the printer engine onto the print
face of the print medium with such a level difference, normal
printing cannot sometimes be carried out on the print face around
the level difference. Specifically, the RFID chip 25 has a border
portion 27 thereof as shown by hatching in FIG. 6, and the print
face of the print medium 24 has the level difference at the border
portion 27 where abnormal printing may be caused. In this
embodiment, therefore, the image information visible to human being
and the code information readable by the optical reading means are
printed on a substantially flat portion of the print face, avoiding
the border portion 27 (level difference).
[0070] As shown in FIG. 6, the RFID tag 11 has an antenna 26 used
for communication between the tag and the RFID reader/writer 5 or
the like. When toner, ink, or the like having electrically
conductive substance such as carbon is used for the printing and
when the image information, bar code, or the like is printed on the
RFID tag to overlap the antenna 26, a trouble can be caused in the
communication between the RFID tag and the RFID reader/writer 5 or
the like. When the toner, ink, or the like includes a magnetic
material such as magnetite, a similar communication trouble can
also be caused due to the influence of magnetism of the magnetic
material. In such cases, by making the printing in a manner
avoiding the antenna 26 or the vicinity thereof, the communication
trouble between the RFID tag and the RFID reader/writer 5 can
advantageously be eliminated.
[0071] Although the RFID chip 25 is carried on the front face side
(on which the print information is printed) of the RFID tag 11 in
this embodiment, the RFID chip 25 may be provided on the rear face
side (opposite the front face) of the RFID tag 11, or may be
embedded into the inside of the RFID tag 11 (for example, the RFID
chip 25 is sandwiched between two recording media, etc.).
[0072] In the following, a printing system according to a second
embodiment of this invention will be explained with reference to
FIGS. 8 and 9.
[0073] FIGS. 8 and 9 are a block diagram and a schematic structural
view of this printing system. In FIGS. 8 and 9, the same elements
as those shown in FIGS. 1-7 are denoted by the same numerals.
[0074] Unlike in the printing system of the first embodiment where
the RFID data consistent with the code information already printed
on the RFID tag 11 is written into the RFID tag 11, in the printing
system of the second embodiment, the RFID data is first read out
from the RFID tag 11 written in advance with the RFID data. Then,
the image information and/or the code information associated with
the RFID data is printed on the RFID tag 11. As in the case of the
first embodiment, the printing system of the second embodiment is
suited, for example, to prepare packaging slips for home delivery
service that are used for goods delivery in large quantity from a
department store or a mail-order selling company. The following is
an explanation of the construction of the printing system.
[0075] Referring to FIGS. 8 and 9, the RFID data is read out by an
RFID readout unit 55 from the RFID chip 25 of the RFID tag 11. On
the basis of the thus read RFID data and various pieces of
information relating to the processing object and read out from the
database 31, the printer controller 22 generates image information
visible to human being. At the same time, from the data ID of the
data record relating to the processing object, image information of
code that is readable by optical reading means is generated. These
pieces of image information (print information) are printed on the
RFID tag 11 by the printer engine 1. Although both the image
information visible to human being and the image information of
code readable by optical reading means can be generated and printed
as mentioned above, only either one of them may be generated and
printed.
[0076] In the printer engine 1, the RFID tag 11 is ordinarily
transported at a given constant speed. Therefore, by taking a time
period required for the RFID tag 11 being transported from an RFID
reader/writer 56 to the transfer means 10 by which the print
information is printed on the RFID tag 11, the consistency is
ensured between the electronic information (RFID data) already
written into the RFID tag 11 and the print information to be
printed on the RFID tag 11 by the printer engine 1. In order to
much improve the consistency, the printing of image information on
the RFID tag and the writing of information into the tag may be
controlled based on a common time basis, as in the later-mentioned
embodiment.
[0077] The RFID data to be written beforehand in the RFID tag 11
may include all or one or more of addressee information, client
information, and goods information. For instance, the RFID data may
include only the data ID of the data record of the processing
object. This is advantageous in that an amount of information can
be reduced, resulting in reduction in the time of writing and
reading the information into and from the RFID tag 11. A further
advantage is to eliminate a fear that private information such as
addressee information and client information is read by third party
from the RFID tag 11.
[0078] In the following, with reference to FIGS. 10 and 11, a
printing system according to a third embodiment of this invention
will be explained.
[0079] FIGS. 10 and 11 are a block diagram and a schematic
structural view of the printing system, respectively. In FIGS. 10
and 11, the same elements as those shown in FIGS. 1-9 are denoted
by the same numerals.
[0080] The printing system of the third embodiment is basically the
same as that of the second embodiment, but differs therefrom in
that the consistency between electronic information and print
information is verified.
[0081] Specifically, as in the second embodiment, the printing
system of third embodiment is adapted to read out the electronic
information (RFID data) from the RFID tag 11 in which such data is
written beforehand, and print the image information and/or the code
information associated with the RFID data onto the RFID tag 11.
This printing system is suited to prepare packaging slips for home
delivery service that are used for goods delivery in large quantity
from a department store or a mail-order selling company. The
following is an explanation on the construction of the printing
system of the third embodiment.
[0082] Referring to FIGS. 10 and 11, in this printing system, the
electronic information written beforehand in the RFID tag 11 is
read out therefrom by the RFID readout unit 55, both the image
information visible to human being and the image information of
code readable by optical readout means are generated by the printer
controller 22, and these pieces of image information are printed on
the RFID tag 11 by the printer engine 1. This construction is the
same as that of the printing system of the second embodiment (see,
FIGS. 8 and 9).
[0083] Next, in the third embodiment, the optically readable code
information printed on the RFID tag 11 is read out by the optical
code readout unit 6, the electronic information (RFID data) is read
out from the RFID tag 11 by an RFID readout unit 57, and the
consistency between the code information and the electronic
information is verified by a data verification subsystem 30 on the
basis of data of the database 31.
[0084] The provision of the data verification subsystem 30 for
verifying the data consistency makes it possible to further improve
the consistency between the electronic information carried on the
RFID tag 11, the image information visible to human being, and the
image information of code (i.e., code information) readable by the
optical readout means. The reading of the code information by the
optical code readout unit 6 and the reading of the electronic
information from the RFID tag 11 by the RFID readout unit 57 may be
made in the reverse order compared to the aforementioned order, or
may be made substantially simultaneously.
[0085] The optical code-reading unit 6, RFID reading unit 55, and
RFID reading unit 57 shown in FIG. 10 correspond individually to
the bar code reader 15, RFID reader/writer 56, and RFID
reader/writer 58 shown in FIG. 11.
[0086] Next, with reference to FIGS. 12-19, a printing system
according to a fourth embodiment of this invention will be
explained.
[0087] FIG. 12 shows an example of the basic construction of the
printing system of the fourth embodiment. As shown in FIG. 12, this
printing system is comprised of the printer engine 1, the RFID
reader/writer 5, and a controller having a spooler 21 and the
printer controller 22. The printer engine 1 and the RFID
reader/writer 5 are connected to the controller 2 that is connected
to the network 3 which is an electronic communication network such
as internet, local area network (LAN), or the like.
[0088] Using the controller 2 and the printer engine 1, the
printing system is adapted to print that drawing data onto the
print-information recording medium, which is "print" activated from
a form layout application program 41 on a client personal computer
4 connected to the network 3.
[0089] The form layout application program 41 running on the
personal computer 4 is a program that is capable of laying out
image information such as text, bar code, etc. on the display
screen of the computer 4, and capable of outputting drawing data
corresponding to the image information to a device such as a
printer driver. The drawing data is data, such as font data or bit
map data, that is so converted as to meet various device interfaces
of an operation system (OS) 42, in order to enable the image
information laid out by the form layout application program 41 to
be output to devices such as display device, printer driver,
etc.
[0090] The client personal computer 4 has a printer driver 43 for
the printing system. The printer driver 43 is a software that has a
function for converting the drawing data prepared by the
application 41 into page description language data (hereinafter
referred to as PDL data) for the printer. The PDL data is data, for
example Postscript data, from which is generated video data that
can be interpreted by the printer controller 22 and is transmitted
to the printer engine 1.
[0091] The controller 2 connected to the network 3 is a computer
that includes the spooler 21 and the printer controller 22, as
mentioned above, and that is adapted to transmit the video data
and/or control data. The spooler 21 is a group of dynamic link
libraries (DLLs) to perform receipt, save (spool), process,
scheduling, distribution, etc. of the PDL data that is output from
the printer driver 43. Ordinarily, the spooler is realized by part
of functions of the operating system of the controller 2.
[0092] The printer controller 22 has a software that has functions
of receiving the PDL data from the spooler 21, converting the same
into the video data and/or control data for the printer engine, and
transmitting the converted data to the printer engine 1. The video
data is bit map data or the like corresponding to the resolution of
the printer engine 1. The control data is data used for execution
of operation or processing of the printer engine 1. The operation
includes form feed or the like. The processing includes, for
instance, acquisition of the status of the printer engine 1 such as
error information.
[0093] The printer controller 22 transmits the printer-engine
control data to the printer engine 1 for control of the operation
and/or processing of the printer engine, and controls the
processing of the RFID reader/writer 5. The processing includes
acquisition of the status of RFID reader/writer such as error
information thereon.
[0094] The printer engine 1 is a printing unit having a function of
printing the image information (print information) on the print
medium 24 of the RFID tag 11 based on the video data transmitted
from the printer controller 22. The RFID reader/writer 5 is a unit
having a function to write the electronic information (RFID data)
into the RFID chip 25 of the RFID tag 11 based on the RFID write
data transmitted from the printer controller 22. The RFID write
data includes control data used to control the RFID reader/writer,
and also includes data that is comprised of text information such
as alphabet or Chinese character to be written into the RFID tag
11. The text information may include, for example, address and name
for direct mail, local ID used to identify each individual
corrugated board box used for distribution, and the like.
[0095] Next, referring to FIG. 13, the flow of printing in this
printing system will be explained. Hereinafter collectively
referred to as print data are: video data transmitted from the
printer controller 22 to the printer engine 1, PDL data transmitted
from the printer driver 43 to the printer controller 22 and
describing information of the video data, and drawing data
transmitted from the form layout application program 41 to the
printer driver 43 and describing information of the PDL data.
[0096] Also collectively referred to as RFID data are: RFID write
data transmitted from the printer controller 22 to the RFID
reader/writer 5, PDL data describing information of the RFID data
and transmitted from the printer driver 43 to the printer
controller 22, original RFID data describing information of the PDL
data and transmitted from the form layout application program 41 to
the printer driver 43, and other data written in the RFID data.
[0097] As shown in FIG. 13, when the print data edited by the form
layout application program 41 running on the client personal
computer 4 is "print" started, drawing data that forms print data
is temporally stored in the operating system (OS) 42 from which the
drawing data is transmitted to the printer driver 43.
[0098] The RFID data edited by the form layout application program
41 is converted into PDL data format by means of the form layout
application program 41 simultaneously when the "print" start is
activated. The converted data is transferred as the original RFID
data to the printer driver 43. The original RFID data includes text
information described in the RFID write data transmitted to the
RFID reader/writer, and also includes control data such as position
information of the RFID write data.
[0099] The printer driver 43 receives the drawing data from the
operating system 42, and receives the original RFID data from the
form layout application program 41. The printer driver 43 converts
these pieces of data into the PDL data for the printer engine 1 and
the RFID reader/writer 5, and transfers the PDL data to an
arbitrary port. The port to which the PDL data is transferred is
generally a printer port, but may be a printer server on the
network or an arbitrary device such as a hard disk on the
network.
[0100] In the following, an explanation will be given for a case
where the PDL data is transferred from the printer driver 43 to the
spooler 21 of the controller 2 on the network 3. The spooler 21 can
temporally save (spool) the PDL data generated by and received from
the printer driver 43, and can also perform scheduling of and
distribution of the PDL data to an arbitrary device. In this
printing system, the printer controller 22 is arranged to read the
PDL data from the spooler 21 as required. The printer controller 22
interprets the PDL data read from the spooler 21, and converts the
same into the video data for printer engine and the RFID write data
for the RFID reader/writer.
[0101] The print data edited by the form layout application program
41 running on the client personal computer 4 is converted into the
PDL data as described above, is transmitted to the printer engine 1
through the printer controller 22, and is printed onto the print
medium 24 of the RFID tag 11 by the printer engine. Similarly as
for the RFID data, the original RFID data is output from the form
layout application program 41 and converted into the PDL data. The
RFID write data is transmitted through the printer controller 22 to
the RFID reader/writer 5, and the text data of the RFID write data
is written into the RFID chip 25 of the RFID tag 11.
[0102] FIG. 14 shows the flow of data between the form layout
application program 41 and the printer driver 43 in the printing
system. As mentioned above, the printer driver 43 is a software
having a function of converting the print data designed by the form
layout application program 41 running on the personal computer 4
into the PDL data for the printer engine. Meanwhile, the printer
driver 43 of this embodiment is enabled to directly communicate
with the form layout application program 41 to handle data other
than the print data edited by the form layout application program
41. Thus, data describing control data and/or text information
output from the form layout application program 41 can be
incorporated into the PDL data.
[0103] In this printing system, the print data to be printed by the
printer engine 1 is transmitted as the drawing data from the form
layout application program 41 to the printer driver 43, and is
converted into the PDL data by the printer driver 43. As for the
RFID write data to be written into the RFID reader/writer, the
original RFID data converted into the PDL data format by the form
layout application program 41 is transmitted from the program 41 to
the printer driver 43, and is then converted into the RFID write
data by the printer controller 22.
[0104] The printer controller 22 interprets a control command
contained in the PDL data output from the printer driver 43, and
generates the video data and the RFID write data that are to be
transmitted to the printer engine 1 and the RFID reader/writer 5,
respectively.
[0105] The print data edited by the form layout application program
41 includes position information representing locations on the
print medium 24 where the text and the bar code are to be
positioned. Similarly, the RFID data designed by the form layout
application program 41 includes position information representing a
location on the print medium 24 at which the RFID data (RFID chip
25) is positioned. These position information contained in the
print data and the RFID data are also held in the PDL data format
that is output from the printer driver 43.
[0106] For instance, when the position of the print data, which is
edited on the editing screen of the form layout application program
41, is altered as shown in FIG. 15, the position information
contained in a control command in the PDL data, prepared by the
printer driver 43 and the form layout application program 41, is
altered accordingly. On the basis of the position information
contained in the control command described in the PDL data, the
printer controller 22 prepares the video data to be output to the
printer engine 1. For instance, the printer drier 43 of this
embodiment is adapted to output, as control command, the position
information represented in units of resolution of the printer
engine 1 in reference to the left upper corner of the recording
medium.
[0107] As mentioned above, the RFID data includes the position
information. For example, the form layout application program 41
displays a rectangular frame on the editing screen to visualize the
location of the RFID data on the print medium 24, as shown in FIG.
15, and holds a coordinate position of the rectangular frame as the
position information of the RFID data. The form layout application
program 41 can set the rectangular frame representing the RFID data
at an arbitrary position. The position information is formed by X-
and Y-coordinate values individually measured in the width
direction and in the transfer direction of the print medium 24 from
the coordinate origin, i.e., the left upper corner of the print
medium 24.
[0108] In the example of FIG. 15, the print data and the RFID data
before alteration are at positions (500, 300) and (100, 50) as
shown in upper part of FIG. 15, whereas the print data and the RFID
data after alteration are at positions (600, 400) and (150, 100) as
shown in lower part of FIG. 15.
[0109] As mentioned above, the original RFID data output from the
form layout application program 41 is output to the printer driver
43. At this time, the original RFID data is transmitted to the
printer driver 43 in the form that is a combination of the X- and
Y- coordinate values, serving as the position information, and the
text information to be written into the RFID reader/writer 5.
[0110] The form layout application program 41 can display and edit
the print data and the RFID data on the editing screen. The print
data is converted by the printer driver 43 into the PDL data to be
transmitted to the printer controller 22, and the RFID data is
converted by the form layout application program 41 into the
original RFID data of PDL data format, which are transferred to the
printer driver 43.
[0111] The printer driver 43 converts the drawing data first
received into the PDL data, and combines the same with the next
received original RFID data to thereby unify the PDL data, making
it easy to synchronize the printing with the writing of the RFID
data.
[0112] The print data is generally given in units of page, and a
page break in printing (page-based printing) is made according to a
control command such as "ESC0C." In this printing system, PDL data
serving as the basis of video data to be printed at an arbitrary
page of the print medium 24 is combined with PDL data serving as
the basis of RFID write data to be written into the RFID chip 25
carried on the same page.
[0113] Using, as a command time basis, a signal transmitted for
every page from the printer engine 1 to the controller, such as for
example, a signal that is called as final raster signal, the RFID
write data is transmitted to the RFID reader/writer 5. This makes
it easy to ensure the consistency between the video data printed on
an arbitrary page of the print medium 24 and the RFID data written
into the RFID chip 25 carried on that page.
[0114] FIG. 16 shows the flow of data between the printer
controller 22, the printer engine 1, and the RFID reader/writer 5
in this printing system. The printer controller 22 communicates
with the printer engine 1, and also communicates with the RFID
reader/writer 5. Synchronization between the printer engine 1 and
the RFID reader/writer 5 is achieved through the printer controller
22.
[0115] The printer controller 22 receives pieces of status data
(print-ready acknowledgement and RFID reader/writer-ready
acknowledgement) individually from the printer engine 1 and the
RFID reader/writer 5, and confirms that preparations for printing
and RFID writing have been completed. Next, when the "print" start
is specified by the form layout application program 41, the
conversion into PDL data is performed by the printer driver 43 and
the form layout application program 41, and the printer controller
22 receives the PDL data for one page. In the printer controller
22, the PDL data for one page is stored in a printer controller
buffer, and is divided into the print data and the RFID data.
[0116] The print data is converted into the video data as explained
before, and is transmitted to the printer engine 1 (video data
transmission). Whereupon, print information is printed on the first
page of the print medium 24. The RFID data for the first page is
stored in the leading address of an RFID buffer table of the
printer controller 22. Next, the data for the second page is also
divided into print data and RFID data, and the print data is
converted into video data and transmitted to the printer engine 1,
whereby the print information is printed on the second page of the
print medium 24. Similarly, the RFID data for the second page is
stored in the second address of the RFID buffer table of the
printer controller 22. Subsequently, the aforesaid processing is
repeated.
[0117] The printer engine 1 transmits the final raster signal to
the printer controller 22 (final raster signal transmission) each
time when the final raster for each page is printed on the print
medium. The printer controller 22 causes the final raster buffer
table to sequentially store the time when the final raster signal
is received. At this time, as in the case of the RFID buffer table,
the printer controller 22 causes the final raster buffer table to
store the time when the final raster signal for the first page is
received into its leading address, and store the time when the
final raster signal for the second page is received into its second
address.
[0118] In the printing system, the writing time of the RFID write
data into the RFID reader/writer 5 is determined from the printing
speed of the printer engine 1, the time when the final raster was
printed by the printer engine, a printing position at which an
image is to be formed on the print medium 24 by the printer engine
1, and a distance between the printing position and the RFID
reader/writer 5. The write time is represented as follows:
RfTime=LsTime+P-RLength/PrintSpeed,
[0119] where RfTime denotes the writing time; LsTime, the time when
the final raster was printed; PrintSpeed, the printing speed; and
P-RLength, the distance between the printing position and the RFID
reader/writer as seen in the print-medium transfer path.
[0120] When writing the data into the RFID chip carried on the
leading page of the print medium 24, a monitoring task of the
printer controller 22 calculates the data writing time, at which
the data is to be written into the RFID reader/writer 5, in
accordance with the aforesaid formula on the basis of the
final-raster printed time LsTime stored in the leading address of
the final raster buffer table, and the like. When the calculated
time is reached (timer count), the RFID write data for the leading
page stored in the leading address of the RFID buffer table is
transmitted to the RFID reader/writer 5 (RFID data transmission).
When the transmission of the RFID write data is completed, both the
data stored in the leading address of the final raster buffer table
and the data stored in the leading address of the RFID buffer table
are deleted. Furthermore, as described later, an RFID writing
acknowledgement signal and/or RFID read data is transmitted from
the RFID reader/writer 5 to the printer controller 22 (RFID writing
acknowledgement signal transmission and/or RFID read data
transmission). Subsequently, similar processing is performed for
the second and subsequent pages until the printing is
interrupted.
[0121] In the printing system, the status of the printer engine 1
can be acquired by transmitting a particular control command from
the printer controller 22 to the printer engine 1, whereby the
printing speed (PrintSpeed) can be determined.
[0122] As explained above, the synchronization between the printing
of print data by means of the printer engine 1 and the writing of
the RFID write data into the RFID reader/writer is achieved by
controlling the transmission, etc. of print data and RFID data by
the printer controller by using, as the common time basis, the
final raster signal that is output from the printer engine 1.
Instead of using the final raster signal output from the printer
engine 1, a signal generated in the printer controller 22 may be
used as the common time basis.
[0123] In this embodiment, an example where the RFID reader/writer
5 is arranged at an ejection section of the printer engine 1 has
been described. Alternatively, the RFID reader/writer 5 may be
arranged at an arbitrary position at the rear of the printer engine
1 so long as the distance (P-Rlength) between printer engine and
RFID reader/writer can be determined. Furthermore, the RFID
reader/writer 5 may be arranged at a paper feed section of the
printer engine 1. In this case, the distance (P-Rlength) between
printer engine and RFID reader/writer in the print-medium transfer
path is calculated to have a negative sign.
[0124] FIG. 17 shows the flow of data in a case where the RFID chip
25 is carried on the print medium 24 at an arbitrary position in
the print-medium transfer direction. In the printing system,
position information can be added to the RFID data of PDL data
format. Thus, the RFID chip 25 can be carried on an arbitrary
position in a given page of the print medium 24, and the RFID write
data can be written into the RFID chip 25 carried on such arbitrary
position. In case that the RFID data frame is moved on the form
layout application program 41 to an arbitrary position in the
direction of transfer of the print medium 24, the writing time of
the RFID write data into the RFID reader/writer 5 is represented as
follows:
RfTime=LsTime+(P-RLength)/PrintSpeed+Rf.sub.--YLength/PrintSpeed,
[0125] where Rf_YLength denote a distance from the head of page of
the print medium to the RFID chip as viewed in the print-medium
transfer direction.
[0126] As explained above, even when the carried position of the
RFID chip 25 on the print medium 24 is changed in the print-medium
transfer direction, the data writing into the RFID chip carried on
the print medium at an arbitrary position in the print-medium
transfer direction can be carried out by changing the writing time
of the RFID write data from the printer controller 22 into the RFID
reader/writer 5. Meanwhile, FIG. 17 shows an example where the
Y-coordinate value representing the position of RFID chip is
changed from 0 to 100, and the writing time RfTime is behind the
writing time for the RFID chip before the positional change by a
time corresponding to the increase in distance Rf_YLength
(=100).
[0127] For a case where the RFID chip is carried on the print
medium at an arbitrary position in the width direction of print
medium, proper writing can be achieved by moving the RFID
reader/writer 5 in the width direction of print medium. To this
end, on the basis of the position data of the original RFID data
transmitted from the form layout application program 41, the
printer controller 22 transmits a control command to move the
position of the RFID reader/writer 5 in the width direction of
print medium, whereby the data writing into the RFID chip carried
on an arbitrary position as viewed in the width direction of print
medium can be realized. The motion of the RFID reader/writer 5 in
the width direction of print medium can be easily realized by a
combination of a known driving unit such as a linear motor or a
pulse motor and an appropriate motion mechanism such as a timing
belt or a screw feeder, for instance.
[0128] Furthermore, the form layout application program 41 is
capable of editing a plurality of pieces of RFID data that are
present in the same one page. When a plurality of the RFID chips 25
are carried on the print medium 24 so as to be spaced apart from
one another in the width direction of print medium, a plurality of
RFID readers/writers 5 are used in order to write the RFID write
data into each of the RFID chips.
[0129] For example, when two RFID chips 25 are carried on the print
medium 24 so as to be spaced apart from each other in the width
direction of print medium as shown in FIG. 18, the form layout
application program 41 first edits two RFID data frames, and
converts pieces of RFID data into PDL data. The printer controller
22 receiving the pieces of RFID data converted into PDL data
determines the number of the pieces of RFID data present in the
same page, and the position of each RFID data in that page.
[0130] In this example, there are two pieces of RFID data having
widthwise position information different from each other, and
therefore, the printer controller 22 recognizes that there are two
pieces of RFID data (two RFID chips 25) in the same page. The
writing of two pieces of the RFID data into the two RFID chips 25
can be realized by means of two RFID readers/writers 5, for
instance.
[0131] Referring to FIG. 18, two RFID chips 25 are carried on the
same page of the print page 24. Specifically, a first RFID chip A
is carried on a widthwise position represented by an X-coordinate
value X1 (for example, 100), whereas a second RFID chip B is
carried on a widthwise position represented by an X-coordinate
value X2 (for example, 400). The printer controller 22 transmits
the RFID write data for the first RFID chip A to a first RFID
reader/writer 51 (writer A), and transmits the RFID write data for
the second RFID chip B to a second RFID reader/writer 52 (writer
B), whereby the RFID data can be written into each of the two RFID
chips that are carried on different widthwise positions in the same
page of the print medium 24.
[0132] The RFID data can also be written into a plurality of RFID
chips carried on the same one page of the print medium 24 as viewed
in the direction of transfer of the print medium. FIG. 19 shows the
flow of data in case that a plurality of, for example, two RFID
chips are carried on different positions in the transfer direction
of print medium.
[0133] As described above, even if the carried position of the RFID
chip 25 on the print medium 24 is changed in the transfer direction
of the print medium, the data writing into the RFID chip can be
carried out by changing the time of data writing into the RFID
reader/writer 5 on the basis of the final raster signal transmitted
from the printer engine 1. Thus, changing the data writing time
makes it possible to perform the data writing into the RFID chip
carried on an arbitrary position as viewed in the transfer
direction. In other words, it is also possible to write data into a
plurality of RFID chips that are carried on different positions in
the same one page as viewed in the print-medium transfer
direction.
[0134] More specifically, in order to perform the data writing, for
example, into two RFID chips that are carried on different position
in the same page of the print medium as viewed in the print-medium
transfer direction, the form layout application program 41 edits
two RFID data frames, as in the case of data writing into two RFID
chips which are different in widthwise position. The two RFID data
frames are juxtaposed in the transfer direction, as shown in FIG.
19.
[0135] Next, the form layout application program 41 converts pieces
of RFID data into PDL data. When receiving the data, the printer
controller 22 determines the number of pieces of RFID data present
in one page and positions of these RFID data in that page. In this
example, a first RFID chip ABC is carried on the print medium 24 at
a transfer-direction position represented by a Y-coordinate value
of 100, and a second RFID chip XYZ is carried at a
transfer-direction position represented by a Y-coordinate value of
300. Since there are two pieces of RFID data having different
information regarding the transfer-direction position as mentioned
above, the printer controller 22 understands that two pieces of
RFID data are present in the same page.
[0136] In accordance with the following formula, each of two RFID
write times for one page is calculated based on the position
information (Rf_YLength):
RfTime=LsTime+P-RLength/PrintSpeed+Rf.sub.--YLength/PrintSpeed.
[0137] After the RFID write times are calculated, the printer
controller 22 writes the RFID write data into the RFID
reader/writer 5 with reference to the RFID write times, whereby it
is possible to write the RFID data into each of the two RFID chips,
the first and second RFID chips ABC, XYZ having different
transfer-direction positions.
[0138] The foregoing examples show that electronic information can
be written into a plurality of RFID chips that are carried on the
print medium at different widthwise positions or different
transfer-direction positions. This indicates that a combination of
the above two methods makes it possible to write the RFID data into
each of four RFID chips having different widthwise positions and
different transfer-direction positions from one another. In this
modification, the explanation has been given for the case where
four RFID chips are carried on the same page of the print medium at
different widthwise and transfer-direction positions. This
invention is also applicable to a case where three or five or more
RFID chips are carried on the same page of the print medium.
[0139] The RFID chip is enabled to be written with electronic
information, without being in contact with the RFID reader/writer
5. Therefore, in case that a plurality of RFID chips are carried on
the same one page of the print medium as mentioned above, when the
electronic data (RFID data) is written into the RFID chip
positioned beneath the RFID reader/writer 5 or in vicinity thereof,
there is a fear that the same electronic information can
erroneously be written also into an adjacent RFID chip. In the case
of a plurality of RFID chips being carried on the same page of the
print medium, it is sometimes possible to remove the just-mentioned
problem that electronic information can be erroneously written into
the adjacent RFID chip, by mounting an electromagnetic shield for
shielding a radio wave from the RFID reader/writer between adjacent
RFID chips.
[0140] In some cases, the above-mentioned problem can be eliminated
by the following countermeasure: An additional RFID reader/writer
is installed at the paper feed section of the printer engine, and
the RFID chip of each RFID tag retains therein an ID that is proper
to each RFID chip. The proper ID is read out by means of the
additional RFID reader/writer, and the printing information is
printed by the printer engine on the print medium of that RFID tag.
Subsequently, on the basis of the proper ID, the RFID reader/writer
installed at the ejection section of the printer engine specifies
the RFID chip to which the data is to be written, whereby each RFID
chip can be written only with the RFID data associated
therewith.
[0141] In the printing system, the RFID data to be written into the
RFID tag is edited on the form layout application program 41. The
RFID data defined on the form layout application program 41 may not
be limited to fixed data. For example, the RFID data may be data
that is retained in an external database. Furthermore, the printer
controller 22 may refer to data in the database. In this case, the
RFID data defined on the form layout application program 41 may be
an database address corresponding to the data in the database. For
example, an address of database provided in a certain computer on
the network 3 is defined as the RFID data by the form layout
application program 41.
[0142] The printer controller 22, receiving the RFID data having
been converted into PDL data, analyzes the RFID data (database
address defined on the form layout application program), reads data
from a database provided in a certain computer on the network 3,
and transmits this data as the RFID data to the RFID reader/writer
5. By doing this, data present in the external database can be
written as RFID data into the RFID chip.
[0143] According to the just-mentioned method, the RFID data to be
written into the RFID tag can be changed simply by changing the
database content, without the need of changing the RFID data on the
form layout application program 41. Moreover, when the RFID data
only includes the database address, the volume of PDL data that is
received by the controller can be reduced on an occasion that PDL
data, in which the RFID data and the print data are mixedly
present, is output from the form layout application program 41
through the printer driver 43.
[0144] In the foregoing example, explanation has been given to a
case where the database is provided in a certain computer on the
network. Alternatively, the database may be provided in a computer
in which the form layout application program 41 is executed or a
computer that constitutes the printer controller 22.
[0145] Further, the printer controller 22 may be adapted to display
the RFID data edited by the form layout application program 41. For
example, the print data can be analyzed from the PDL data by the
printer controller 22, and the video data used for printing by the
printer engine 1 can be displayed on the screen of the printer
controller 22. The RFID write data can also be displayed on the
screen of the printer controller 22.
[0146] In order to allow the data to be discriminated, the printing
system is arranged to display the video data in black in color and
the RFID write data in blue. All the RFID write data can be
displayed on the screen of the printer controller 22. However, if
the RFID write data is large in data size, part of the RFID write
data, for example, data corresponding to the leading five
characters, can be displayed. Alternatively, some mark representing
that there is the RFID write data may be displayed, and all the
RFID write data may be displayed on a different operation
screen.
[0147] There is a case where the printing is performed in a
printing company by using print data that is prepared by a data
preparation company, which is different from the printing company,
by using the form layout application program 41. In such a case,
the print data prepared by the data preparation company is
transmitted to the printing company by way of a communication line
such as internet or provided in the form of external recording
medium such as optical magnetic disk. The printing company receives
the print data by means of the printer controller, and performs the
printing onto the print medium by using the printer engine.
[0148] At that time, there sometimes occurs the following problem.
When the position of preprinted ruled lines or specified print
frames or RFID chips carried on the print medium is slightly
shifted from the intended one, much labor and long time are needed,
resulting in inefficiency, since the conventional art cannot enable
the printing company to edit the print data. Specifically, in such
a case, the printing company is required to contact the data
preparation company, and corrections to the printing position or
RFID frame position must be made by the data preparation company by
using the form layout application program 41.
[0149] According to the printing system, the RFID write data can be
edited even by means of the printer controller 22. For example, the
position information of the RFID write data to be written into the
RFID reader/writer can be changed. The printing system of this
invention having the just-mentioned function can edit the RFID
write data by means of the printer controller 22, without the need
of tracing back to the form layout application program 41.
[0150] By utilizing such function of the printing system, when
carried positions of RFID chips on the print medium, etc. must be
changed, data edition can be performed even by the printing company
which is different from the data preparation company, whereby the
efficiency of printing operation can be improved.
[0151] When the RFID chip is damaged for any reasons, electronic
information cannot be written into the RFID chip, and in most
cases, such damage cannot be found out by simply looking at the
RFID chip carried on the print medium. Furthermore, the electronic
information already written into the RFID chip cannot be
ascertained.
[0152] According to the printing system of this invention, the
printing system can be stopped in dependence on the written state
of RFID data. Specifically, as shown in FIG. 16, after the RFID
write data is transmitted to the RFID reader/writer 5, the RFID
reader/writer 5 performs RFID-writing acknowledgement signal
transmission. The printer controller 22 receives the status
(acknowledgement signal) of the RFID reader/writer 5, thereby
obtaining information that indicates whether or not the writing of
RFID write data has been completed. Therefore, it is possible, for
example, to configure the printer controller 22 such that it
transmits a control command to stop printing to the printer engine
1 so as to interrupt the printing when the writing of RFID write
data is failed. In addition, an error message can be displayed on
the screen of the printer controller or of a computer on the
network to notify the operator of the printing being stopped.
[0153] When there occurs an error, the page of the print medium on
which the damaged RFID chip is carried is removed, and then an
arbitrary page can be specified on the printer controller 22,
without the need of tracing back to the form layout application
program 41, whereby the reprinting and the writing of RFID write
data into the RFID reader/writer 5 (the writing of RFID data into
RFID chip) can be made. Moreover, the print page to be reprinted
can be specified by specifying the error page by means of the
printer controller 22 or by displaying the print data and the RFID
write data on the printer controller 22, as mentioned above.
[0154] According to the prior art system in which synchronization
between printing and writing of RFID data cannot be achieved, when
the RFID chip is damaged so that the writing of RFID data cannot be
completed, the page in question must be printed again from the
application. In some cases, the consistency cannot be ensured
between the print information printed on each page of the print
medium after the printing is restarted and the RFID data written
into the RFID chip carried on the same page of the print medium. In
the printing system of this invention, the consistency between the
print data and the RFID data can be ensured even in the reprinting,
which is required when the RFID data writing cannot be made due to
the RFID chip being damaged.
[0155] In the foregoing example, the printing is forcibly stopped
when there occurs a writing failure of RFID data into the RFID
chip. Alternatively, the printer controller 22 may store the page
for which the writing of RFID data into RFID chip (the writing of
RFID write data into RFID reader/writer) has been failed, so that
the operator can ascertain, during or after completion of the
printing, the page for which the data writing failure has been
caused. Furthermore, the printing system may be arranged to carry
out the rewriting to the page for which data writing failure has
been caused, without the need of tracing back to the form layout
application program 41. The error information may be saved in a
file of the printer controller 22 or the computer on the
network.
[0156] In the foregoing example, a selection can be made on a menu
on the printer controller 22 whether the printing must be stopped
or not upon occurrence of data writing failure. Alternatively, such
selection may be set on the form layout application program 41, and
setting information may be contained in PDL data. By doing this,
the operation of the printing system upon occurrence of data
writing failure can be selected in advance, without the need of
making selection on the menu on the printer controller 22.
[0157] On the form layout application program 41, an arbitrary
setting information can be converted into PDL data. Therefore, if
the format of RFID data written into the RFID tag is to be changed
depending on the type of RFID tag, the type of RFID tag may be
added to PDL data. As explained previously, the operation or
processing of the printer engine and/or the RFID reader/writer can
be set on the form layout application program 41, from which the
setting is output to the printer controller in the form of PDL
data.
[0158] At the time of writing the RFID write data by means of the
RFID reader/writer 5, the RFID data written into the RFID chip of
the RFID tag may be read therefrom, and the read RFID data may be
transferred from the RFID reader/writer 5 to the printer controller
22 (RFID read data transmission), as shown in FIG. 16. In addition
to information indicating whether or not the data writing has been
completed, the printer controller 22 receives the RFID data
obtained from the RFID tag, and therefore, the printer controller
22 can verify the RFID data written into the RFID tag.
[0159] In some cases, the writing speed of RFID data into the RFID
tag is slower than the printing speed of the printing engine 1. The
time required for data writing into the RFID tag varies depending
on the volume of RFID data. In this regard, the printing speed of
the printer engine 1 may be controlled in advance by the printer
controller 22 in dependence on the RFID data amount, whereby a
writing failure of RFID data can be prevented.
[0160] On the basis of the received PDL data, the printer
controller 22 can determine an amount of RFID write data to be
written into the RFID reader/writer. When the amount of RFID write
data is small, the printing speed of the printer engine 1 is
maximized to increase the throughput of the printing system. On the
other hand, when the amount of RFID write data is large, the
printing speed of the printer engine 1 is decreased so that the
RFID write data can be written into the RFID reader/writer, whereby
a writing failure of RFID write data and hence a writing failure of
RFID data into RFID chip can be prevented.
