Description
FIELD OF THE INVENTION
[0001] The present invention relates to a printer controlling
device which displays a load state of at least one printer
connected through a network, a printer controlling method, and a
computer program for allowing a computer to execute the method is
stored.
BACKGROUND OF THE INVENTION
[0002] Conventionally there exists a service called "copy service",
"printing service" and the like in which a designated document
requested by a customer (mainly, company) is printed by a
designated number of sheets, and the printed sheets are bound in a
designated method and supplied.
[0003] A printing request is carried out in such a manner that a
draft recorded in a paper medium or electronic medium (FD, MO,
CD-ROM or the like) and a printing instruction in which the number
of copies of the draft, a binding method, a delivery date and the
like are written are mailed to a dealer who provides the
above-described service (this is called "new order"). When a draft
which was also previously requested to be printed is re-requested
to be printed, the draft which is in storage on the side of the
dealer may be designated and the number of copies and the like may
informed on telephone (this is called "repeated order").
[0004] On the side of the dealer, processing procedure or
processing time periods are determined by instinct or experience of
a person in charge of this job (or task) while taking into account
the number of prints, delivery date, limit of personal or physical
resource and the like for each of requests received from an
indefinite number of customers. According to this schedule, the
designated draft is copied by a copier, or the draft is printed by
a printer connected to a personal computer, and finally the copied
or printed sheets are confirmed and collated and delivered to the
customer.
[0005] Whereas, there is realized a system in which the printing
request from a customer is received online through Internet, and
scheduling or print out are automatically carried out using a print
server and a plurality of printers connected to the print
server.
[0006] For example, a customer accesses a Web page provided by a
dealer from a personal computer of his own company, the customer
inputs necessary information such as the number of copies on a
print requesting form (job ticket), and the form is sent together
with document data to be printed, and the printing of the document
can be ordered.
[0007] The dealer received this order selects a printer that can
complete already allocated jobs fastest from various printers
connected to the server through LAN. Then, the dealer adds this new
print-job to the last one of the print-waiting jobs.
[0008] If the new job had short delivery date and could not wait
for completion of other jobs, the new job may exceptionally be
processed as an interruption before the other waiting jobs. More
efficient job scheduling system is also realized in which a large
job is divided into some of small jobs and they are processed by a
plurality of printers (concurrent printing), or a job is divided
into small jobs such the loads of printers becomes equal to each
other (averaging printing), or a job is distributed such that cost
is minimized (optimizing printing).
[0009] However, in the above conventional art, there is a problem
that it is difficult to grasp the total volume of loads of the
entire system or distribution state of loads to printers, including
how much jobs the entire system has, or the amount of jobs of each
printer, or which printer does not have allocated jobs.
[0010] FIG. 21 is an explanatory view showing one example of a
print-job list window displayed on a conventional print server.
Since time required for processing each job is found only roughly
from file size or the number of copies, an item of printing time
calculated by any calculation equation may be provided in addition
to them (or instead of them). However, even with this item, the
printing time of each job is only indicated clearly, total printing
time required for processing all of jobs distributed to the
printers, and the total printing time required for processing all
of jobs of the entire system must be obtained by another
calculation.
[0011] In order to estimate when a job is processed by a printer to
which the job is allocated, printing time of previous jobs must be
summed up. Therefore, it is complicate to check whether each job
can be processed in time point by point. In association with
unclearness of processing time period of job, it is difficult to
find a total volume of jobs processed for a given time period and a
total volume of jobs of each printer.

DETAILED DESCRIPTION
[0040] Embodiments of a printer controlling device which displays a
load state of at least one printer connected through a network, a
printer controlling method, and a computer program for allowing a
computer to execute the method is stored will be explained in
detail with reference to the accompanying drawings.
[0041] System Construction of a Printing System:
[0042] First, the entire printing system including a printer
controlling device of an embodiment of the invention will be
explained. FIG. 1 is an explanatory view showing the system
construction of the printing system including a printer controlling
device according to the embodiment of the present invention.
[0043] In FIG. 1, a reference number 101 represents a user client,
and is a computer used by a customer for ordering printing
operation to a dealer. A Web browser is started from this computer,
and if a print-requesting Web page on a later-described WWW server
104 is accessed, a document to be printed and a job ticket in which
its printing condition is written can be sent.
[0044] In FIG. 1, the printing system comprises later-described a
reception client 102, a managing client 103, a WWW server 104, a
print server 105, a document managing server 106 and a plurality of
printers 107. The computer and the printers are connected to each
other through LANs.
[0045] A reference number 102 represents a reception client, and is
a computer used by a person in charge of the dealer who received
the order by means of telephone or mail in stead of a customer who
does not have a computer or network. The person uses the reception
client 102 for inputting a document to be printed and a job ticket.
The reception client 102 has the same function as that of the user
client 101.
[0046] A reference number 103 represents a managing client, and is
a computer used by a person in charge of the dealer for managing
the printing operation ordered from a customer. If a print-managing
Web page on the WWW server 104 is accessed from the Web browser,
the document to be printed and the job ticket can be registered,
retrieved, deleted and managed.
[0047] The reference number 104 represents the WWW server, and is a
computer for supplying three kinds of Web pages, i.e., a
print-requesting Web page, a print-managing Web page and a document
managing server Web page, as well as Web applications for the Web
pages. If the WWW server 104 received a new print order from the
user client 101 or the reception client 102 through the above Web
page, the WWW server 104 transfers the order to the print server
105 which will be described later.
[0048] The print server 105 controls the later-described printer
107 to allow the latter to process a print-job sent from the user
client 101 or the reception client 102. Further, as will be
described later, the print server 105 displays, on a screen,
accumulation state, a progress state, an operating status of each
printer in real time and graphically.
[0049] A reference number 106 represents a document managing
server, and is a computer for accumulating and managing a document
to be printed and a job ticket. The document managing server 106
receives acquisition request from the print server 105, and
retrieves and sends a document to be held and a job ticket.
[0050] The reception client 102, the managing client 103, the WWW
server 104, the print server 105 and the document managing server
106 may not always individual computers, and one computer may have
all of the above functions.
[0051] Each of the printers 107 forms a paper image from a document
to be printed in accordance with control of the print server 105,
and prints the imaged document on a predetermined sheet of paper in
accordance the designated condition.
[0052] A hardware construction of the printer controlling device
(concretely, print server 105) of the embodiment of the invention
will be explained. FIG. 2 is an explanatory view showing a hardware
construction of the print server 105 of the embodiment of the
invention.
[0053] In FIG. 2, a reference number 201 represents a CPU for
controlling operation of the entire apparatus. A reference number
202 represents a ROM in which a basic input/output program is
stored. A reference number 203 represents a RAM used as a work area
of the CPU 201.
[0054] A reference number 204 represents a HDD (hard disk drive)
which controls read/write of data with respect to a HD (hard disk)
205, and the reference number 205 represents the HD storing data
written in accordance with control of the HDD 204. A reference
number 206 represents a FDD (floppy disk drive) which controls
read/write of a FD (floppy disk) 207. The reference number 207
represents is the FD as one example of a detachable storage medium
for storing data written in accordance with control of the FDD
206.
[0055] A display 208 displays a cursor, a window and various data
such as characters and images. A network board 209 is connected to
a network NET such as LAN through a network cable 210 such as a
twisted pair wire, and functions as an interface between the
network NET and the CPU 201.
[0056] A keyboard 211 has a plurality of keys for inputting
characters, numerical values, various instructions and the like. A
mouse 212 is used for selecting and executing various instructions,
selecting subject to be processed, and moving the cursor. A CD-ROM
213 is a detachable storage medium. A CD-ROM drive 214 controls
read of data with respect to the CD-ROM 213. A bus or cable 200 is
used for connecting the above elements.
[0057] Next, a functional construction of the printer controlling
device (print server 105) of the embodiment of the invention will
be explained. FIG. 3 is an explanatory view functionally showing
the construction of the print server 105 of the embodiment. In FIG.
3, only minimum functions required for explaining the present
invention are illustrated, and other portions are omitted.
[0058] As shown in FIG. 3, a Web interface 301 controls
communication with the WWW server 104, and receives various
requests such as a print-order, i.e., a register-request of a
print-job transferred from the user client 101 or the like through
the WWW server 104.
[0059] As requests to be received, in addition to the register of a
print-job, there are detail confirmation and state confirmation of
print-job which have already been registered and a list display of
print-jobs registered in the past. Therefore, the Web interface 301
first judges which request an input request is. If the input
request is register of a print-job, a document to be printed and
its job ticket are output to the document managing server 106
through the document managing server interface 302, and to a
later-described printer allocating section 307 (when a printer
allocation at the time of input using a dialog in later-described
FIG. 9 is selected).
[0060] The document managing server interface 302 controls
communication with the document managing server 106, and sends
register request of a document to be printed and a job ticket input
from the Web interface 301 to the document managing server 106, or
sends acquisition request of already registered document and job
ticket and receives the document and the job ticket.
[0061] A database managing section 303 receives orders from a
later-described printer interface 304, a printing time calculating
section 306, and a printer allocating section 307, and writes the
orders into a print-job table 303a, a print schedule table 303b and
a printer table 303c.
[0062] The print-job table 303a is a table for holding details of
contents of a print-job input from the user client 101 or the like.
FIG. 4 is an explanatory view showing one example of items of
print-job table 303a. In the print-job table 303a, various printing
conditions such as the number of copies ("NUM" in FIG. 4) and the
number of printing pages ("OPAGE" in FIG. 4) are registered in
association with job IDs.
[0063] The print schedule table 303b is a table for holding printer
slated to process, a current state of each job registered in the
print-job table 303a. FIG. 5 is an explanatory view showing one
example of items of print schedule table 303b. In the print
schedule table 303b, a printer slanted to process ("PRNT" in FIG.
5), a current state ("KFLG" in FIG. 5), printing time ("TIME" in
FIG. 5) and the like are registered in association with job
IDs.
[0064] The printer table 303c is a table for all the printers 107
managed by the print server 105. The table holds a group, a
scheduling system, property and a current state of each printer in
the group. FIG. 6 is a schematic explanatory view showing one
example of items of the printer table 303c. In FIG. 6, a symbol "*"
represents a group selected by an inputting section 305 as will be
described later, and accumulation states of jobs for printers in
this group are collectively displayed in a later-described schedule
view.
[0065] Among the items of the printer table 303c shown in FIG. 6,
contents of "state" item are temporarily rewritten by notice from
the printer interface 304 as will be described later. Contents
other than that of the above item are set by dialogs shown in FIGS.
7 to 9.
[0066] In the dialog shown in FIG. 7, if an adding button 701 is
pushed, a dialog shown in FIG. 8 is displayed, and an arbitrary
group name such as "Printer B" is input for example. If a desired
printer is selected from printers which can be added and an adding
button 801 is pushed, the selected printer is added to printers
managed by "Printer B" group. If a next button 802 is pushed, a
dialog shown in FIG. 9 is displayed, and a scheduling system and
the like of the added group are set.
[0067] In "operation of receiving time" item of the dialog shown in
FIG. 9, any of the following schedule systems is selected: (a) a
later-described dialog in FIG. 10 is displayed to allow an operator
to manually allocate a printer for a new job simultaneously with
input of the new job, (b) the printer is automatically allocated by
the later-described printer allocating section 307 simultaneously
with input of the new job, and (c) the printer is not allocated
when the new job is input, and the operator is allowed to manually
allocate the printer in the later-described main view or the
schedule view. Here, it is assumed that (a) is selected for the
"Printer B" group and "Printer A" group as shown.
[0068] In "parallel printing" item in dialog shown in FIG. 9, when
the number of copies of the jobs exceeds a threshold value, it is
determined in the dialog shown in FIG. 10 to be mentioned below
whether the job is divided and distributed to a plurality of
printers at the default, and if it is determined to divide the job,
the threshold value is set. If a complete button 901 is pushed, the
set contents in dialogs in FIGS. 8 and 9 are written in the printer
table 303c by the database managing section 303.
[0069] The printer interface 304 controls the communication with
the printers 107, and whenever the completion of a job is informed
from any of the printers, the database managing section 303 is
requested to retrieve a next job allocated to that printer from the
print schedule table 303b, and if the next job was found, details
of that job held in the print-job table 303a is returned.
[0070] A name of a document to be printed (or information capable
of specifying that document such as ID) is extracted from the
received job details, and data of that document is obtained through
the document managing server interface 302. Necessary information
such as data of the document to be printed and the number of copies
is sent to the printer 107 designated by the print schedule table
303b, and the job is processed.
[0071] The printer interface 304 receives the states sent from the
printers at constant intervals. The printer interface 304 requests
the database managing section 303 to rewrite the "state" item of
the printer table 303c into a new state. States of jobs are found
from the states of the printers, the database managing section 303
is requested to renew the states of the jobs held in the print
schedule table 303b.
[0072] The inputting section 305 inputs various instructions such
as selection instructions of a job or a printer displayed in the
later-described schedule view, switching instructions of the
printer group, allocation instructions of printers, and
interruption instructions of job. The inputting section 305
corresponds to "designating unit" in claims, and a portion of
process carried out by the inputting section 305 corresponds to
"designating step" in claims.
[0073] The printing time calculating section 306 calculates, when
requested from the later-described printer allocating section 307,
time expected to be required for processing individual input job,
i.e., printing time using a printing speed of a printer to which
the job is allocated, in accordance with the following
equation:
[0074] printing time (min)=60 (min).times.the number of
copies.times.the number of printing pages/printing speed of printer
(ppm (prints per minute)).
[0075] When printing time of a job which is not allocated to a
printer is to be calculated, an average value of printing speeds of
all managed printers is used as the printing speed of the
printer.
[0076] The printing time informed the printer allocating section
307 from the printing time calculating section 306 is written into
the "printing time" item of the print schedule table 303b by the
database managing section 303 requested from the printer allocating
section 307. Whenever a constant time is elapsed, the printing time
calculating section 306 requests the database managing section 303
to read the printing time which is being printed from the print
schedule table 303b, and its value is re-calculated.
[0077] An equation in that case is, for example, as follows:
[0078] printing time (min)={60(min).times.the number of
copies.times.the number of printing pages/printing speed of printer
(cpm)}-(60 (min).times.the number of printed sheets (=the number of
already printed sheets)/printing speed of printer (cpm)}.
[0079] The database managing section 303 is requested to rewrite
the re-calculated printing time into the print schedule table
303b.
[0080] As apparent from the above description, the printing time
that is calculated and recalculated by the printing time
calculating section 306 and held by the print schedule table 303b
is residue time expected to be required from the current time in
the strict sense, and the printing time is reduced as the job is
processed and when the job is completed, the printing time becomes
zero.
[0081] The printing time calculating section 306 corresponds to
"calculating unit" and "second calculating unit" in claims, and
processing carried out by the printing time calculating section 306
corresponds to "calculating step" and "second calculating
step".
[0082] When (a) is set in the "operation of receiving time" item of
the dialog shown in FIG. 9 as described above, the printer
allocating section 307 displays a dialog as shown in FIG. 10
simultaneously with input of a new job from the Web interface 301.
In this dialog, a printer to which the new job is to be allocated,
and the number of allocation sections to the printers are set, and
if a next button 1001 is pushed, a dialog shown in FIG. 11 is
displayed.
[0083] In this dialog, precedence of jobs is set, and if a
completion button 1101 is pushed, a job ID (serial number) is given
to the new job. At that time, if the job has been divided and
distributed to a plurality of printers in the dialog in FIG. 10,
i.e., a parallel printing has been instructed, a job ID is given to
a parent job before divided, and job IDs in which a serial number
particular to the small job is added to the job ID of the parent
job is given to each of the small jobs after division.
[0084] The printer allocating section 307 requests the printing
time calculating section 306 to calculate the printing time of each
job, and outputs the printing time, the job ID, contents set in the
dialogs in FIGS. 10 and 11, and a job ticket received from the Web
interface 301 to the database managing section 303.
[0085] In the database managing section 303, necessary information
is extracted from the input information, and the extracted
information is written into each item of the print-job table 303a
and the print schedule table 303b. In the print-job table 303a, a
record is formed in unit requested from the customer in the
print-job table 303a, i.e., in unit of parent job, and a record is
formed in the print schedule table 303b in a unit actually
processed by the printer, i.e., in a unit of the small job.
[0086] If a cancel button 1002 in the dialog in FIG. 10 or a cancel
button 1102 in the dialog in FIG. 11 is pushed, the printer
allocating section 307 outputs only the job ID, the printing time
and the job ticket received from the Web interface 301 to the
database managing section 303. Thus, the "PRNT" item in the print
schedule table 303b stays blank.
[0087] A job in which at least a job ID is written in the print-job
table 303a and the print schedule table 303b but a printer is not
determined is called "printer-unallocated" or "unallocated" job
hereinafter.
[0088] The printer allocating section 307 corresponds to
"allocating unit" in claims, and processing carried out by the
printer allocating section 307 corresponds to "allocating step" in
claims.
[0089] A main view display section 308 reads out necessary
information from each table of the database managing section 303,
and displays a main view shown in FIG. 12. In a window shown in
FIG. 12, an interior thereof is roughly divided into three. All the
printers managed by the print server are displayed in a left region
1201 in a tree structure.
[0090] Jobs which are not completed but scheduled a printer
selected here or all printers in a selected group are listed in a
right upper region 1202. Jobs which have already been completed in
the printer are listed in a right lower region 1203.
[0091] This window is basically similar to a conventional job list
window shown in FIG. 21. Thus, it is difficult, in some cases, to
find which printer in a group has how much load, or when a job
allocated to the printer is completed. Thereupon, if a schedule
view icon 1204 is pushed in the main view, a schedule view showing
the above information in an easy manner is displayed instead of the
above window.
[0092] A schedule view display section 309 comprises a job graph
display section 309a, a time scale display section 309b, a guide
bar display section 309c, an in-process job information display
section 309d, a printer state display section 309e, all-unallocated
job information display section 309f, a selected job information
display section 309g, and a interruption position display section
309h.
[0093] FIG. 13 is a schematic explanatory view showing a
construction of a schedule view displayed by the schedule view
display section 309. The window is divided into an allocated job
display area 1301 and an unallocated job display area 1302. The
areas are respectively provided with time scale display areas 1303
and 1304.
[0094] The allocated job display area 1301 is further divided into
blocks 1301a to d for each of the printers. As shown in FIG. 13,
the window is divided for each of the printers horizontally, but
the window may be divided vertically. Each block comprises a job
graph display area 1305, an in-process job information display area
1306 and a printer state display area 1307.
[0095] The unallocated job display area 1302 comprises a single
block. The block comprises a job graph display area 1305,
all-unallocated job information display area 1308 and a job
information display area 1309.
[0096] Each of the job graph display areas 1305 is drawn by the job
graph display section 309a. The job graph display section 309a
corresponds to "display unit" and "second display unit" in claims,
and processing carried out corresponds to "display step" and.
"second display step" in claims.
[0097] The time scale display areas 1303 and 1304 is drawn by the
time scale display section 309b. The time scale display section
309b corresponds to "time scale display unit" in claims, and
processing carried out by this unit corresponds to "time scale
display step" in claims.
[0098] Although it is not illustrated in FIG. 13, a guide bar 1410
shown in FIG. 14 is drawn by a guide bar display section 309c. The
guide bar display section 309c corresponds to "guide bar display
unit" in claims, and processing carried out by this unit
corresponds to "guide bar display step" and "guide bar re-display
step".
[0099] The in-process job information display area 1306 is drawn by
the in-process job information display section 309d. The in-process
job information display section 309d corresponds to "in-process job
information display unit" in claims, and processing carried out by
this unit corresponds to "in-process job information display
step".
[0100] The printer state display area 1307 is drawn by the printer
state display section 309e. This printer state display section 309e
corresponds to "printer state display unit" in claims, and
processing carried out by this unit corresponds to "printer state
display step".
[0101] The all-unallocated job information display area 1308 is
drawn by the all-unallocated job information display section 309f,
and this all-unallocated job information display section 309f
corresponds to "all-unallocated job information display unit" in
claims, and processing carried out by this unit corresponds to
"all-unallocated job information display step" in claims.
[0102] The selected job information display area 1309 is drawn by
the selected job information display section 309g. This selected
job information display section 309g corresponds to "selected job
information display unit" in claims, and processing carried out by
this unit corresponds to "selected job information display step" in
claims.
[0103] Although it is not illustrated in FIG. 13, a later-described
interruption position pointer 1901 in FIG. 19 is drawn by the
interruption position display section 309h, this interruption
position display section 309h corresponds to "interruption position
display unit", and processing carried out by this unit corresponds
to "interruption position display step".
[0104] FIG. 14 is an explanatory view showing one example of the
schedule view displayed by the schedule view display section 309.
First, in a job graph display area 1405 of each the allocated job
display area 1401, jobs allocated to that printer but not completed
are displayed each with a predetermined shape having a length
proportional to its printing time (e.g., rectangular, and
"rectangular shape" hereinafter), and are displayed in the order
without leaving space. One dot gap of the same color as the
background color is provided between jobs so that its boundary can
easily be seen.
[0105] A bar-like rectangular shape formed by arranging the
rectangular shapes of jobs allocated to the same printer at
distances of one dot is called "job graph" hereinafter. Since a
length of each rectangular shape is proportional to a printing time
of each job, the length of each job graph is proportional to a
total processing time accumulated in that printer, i.e.,
proportional to a load of each printer. Therefore, it is possible
to grasp magnitude of a load of each printer through intuition by
the length.
[0106] When a new job was input, or when a printer slated to
process an existing job was determined or changed, or when a job or
printer is changed in state, or when printing time was
re-calculated as the printing operation proceeded, in short, when
data was written or rewritten in any of tables held in the database
managing section 303, the job graph display section 309a refers to
each written or rewritten table, and each job graph is re-displayed
(refreshed).
[0107] Since the printing time of a job which is being printed is
re-calculated and gradually reduced as the printing operation
proceeds, the length of the rectangular shape corresponding to that
job is also shortened whenever the job graph is displayed. Since a
job which is being printed is always displayed at a top of the job
graph, i.e., on the side of a starting point of the later-described
time scale, if the length of the top rectangular shape is
shortened, subsequent rectangular shapes are moved into the
starting point correspondingly. More intuitively, the job graph of
each printer sequentially moves toward the top, here, leftward as
the time is elapsed, and a point ahead of the starting point comes
out from the screen. Therefore, the progress state of a job by each
printer can intuitively be grasped by the movement of the job
graph.
[0108] Color or pattern of each rectangular shape in the job graph
shows a job state corresponding to that rectangular shape, and when
the job graph is re-displayed, a new state of each job is renewed.
FIG. 15 is an explanatory view showing a corresponding relation
between a job state and a color or pattern of a rectangular
shape.
[0109] Characters such as "1", "2" and the like shown on a right
upper corner in the rectangular shape show that a job shown with
the rectangular shape is a small job divided from a parent job, in
other words, that job is a subject of parallel printing. Since
common characters are added to small jobs divided from the same
parent job, it is easy to find when a job which is to be printed in
parallel by a plurality of printers by which printer.
[0110] Although the characters are indicated in the rectangular
shape, the invention is not limited to this, and the characters may
be indicated near the rectangular shape so that it can be found
that the characters indicate the rectangular shape. The same
numbers are used in this embodiment, but the invention is not
limited to this, and the same characters maybe used, or the same
graphics or pictures such as icons may be used. Further, by
indicating one of jobs divided by an icon, the other one of the
divided jobs may be indicated in a different manner.
[0111] Accumulation states of jobs of a plurality of printers in a
selected group, here, printers from "Printer A1" to "Printer A4" in
the "Printer A" group are simultaneously displayed in the allocated
job display area 1401.
[0112] In order to see an accumulation state of a job in other
group, switching instructions of displayed printer groups displayed
are input from the inputting section 305. More specifically, as
shown in FIG. 16, a desired group is clicked by a mouse 212 from a
pull-down list 1413 at an upper portion in the window. If the
printer table 303c switches the group to another group by the
database managing section 303 requested by the inputting section
305, each portion of the schedule view display section 309 displays
an accumulation state of a job and detailed information of a job
which is being processed about each printer in the newly selected
group instead of the group displayed heretofore.
[0113] In the schedule view shown in FIG. 14, time scales are
displayed in time scale display areas 1403 and 1404 respectively.
Elapsed time from the current date and time is displayed in the
time scale, and its unit is minute.
[0114] Relative magnitude of loads of the printers can be grasped
by lengths of job graph even if there is no time scale, but
magnitude of absolute load such as length of printing time can not
be found. If a terminal end of the job graph of a printer is
located "after 120 minutes" on the scale for example, it can be
found that job of remaining 120 minutes is accumulated in that
printer.
[0115] For example, a rectangular shape whose terminal end is
located "after 300 minutes" on the scale shows a job which will be
completed after 300 minutes (5 hours). Therefore, if there is a job
which must be completed within that day, i.e., 17:00 that is
quitting time at noon, if a user sees whether the terminal end of
the rectangular shape showing that job is closer to the starting
point than "after 300 minutes" on the scale, it is possible to
easily judge whether the job will be completed within the
deadline.
[0116] In the schedule view shown in FIG. 14, a guide bar 1410 is
displayed. The guide bar 1410 passes through a point on the scale
and astride a job graph in a direction perpendicular to the point.
Each straight line is cut but this is due to design, and each the
straight line is one line in principle.
[0117] If "guide bar display" is selected from "display menu", one
guide bar 1410 is displayed. Whenever the "guide bar display" is
executed, a new guide bar 1410 is displayed. Therefore, a desired
number of guide bars 1410 can be set in the window. The guide bar
1410 can be moved to a desired position on the scale by the mouse
212.
[0118] The guide bar 1410 can be used variously. For example, when
a job graph ending at its left side and a job graph ending at its
right side are mixed, this means that jobs are not equally
distributed to the printers. Therefore, it is possible to equalize
the levels of loads of printers by re-allocating a job of a printer
having a great load to a printer having a small load.
[0119] The guide bar 1410 can also be used for checking whether
processing time periods of the jobs which are printed by a
plurality of printers in parallel are varied. When some of small
jobs divided from the same parent job exist on the left side of the
guide bar 1410 and other small jobs exist on the right side, the
processing-time periods of the small jobs are varied and results of
print can not be coordinated efficiently. Thus, some of jobs are
re-allocated so that processing time periods of the small jobs
becomes substantially the same.
[0120] The guide bar 1410 can be used for grasping whether how much
time-out jobs are generated. When there exists two hours until
quitting time, if the guide bar 1410 is set to "after 120 minutes",
a job which lies off rightward is the time-out job. In association
with this, the guide bar 1410 can be utilized for checking whether
a job is completed within the deadline.
[0121] The guide bar 1410 is sequentially moved toward the starting
point on the scale by the elapsed time from the setting time, and
if it reached the starting point, the bar is erased. Alternatively,
if the bar is set on a position of after 120 minutes on the scale,
the bar may be erased after just 120 minutes. Therefore, if the
guide bar 1410 is set on the terminal end of a job which a user
decided to process up to here today, it is possible to grasp
remaining time (a target can be achieved after 30 minutes) to
achieve a target.
[0122] In the block of each printer, detailed information of a job
which is being processed by each printer, more specifically, name
of document, user's name, memo, job ID, progress state and an
in-process job information display area 1406 for displaying output
form are provided. In the drawing, an area for displaying the name
of document, the user's name and the memo, and an area for
displaying the job ID, the progress state and the output form are
separated from each other, but this is convenient, in term of
design, for keeping balance with respect to the later-described
unallocated job display area 1402, and the areas may not be divided
and collectively displayed.
[0123] The progress state is indicated by "the number of printed
sheets"/"total number of prints" concretely.
[0124] The number of printed sheets is the number of sheets which
have already been printed, and the total number of prints is
obtained from "the number of copies.times.the number of printing
pages".
[0125] The output form shows a classification of printing states,
i.e., a state in which the job is collectively processed by that
printer (collective print), a state in which the job is divided
into a plurality of jobs, and the jobs are processed by a plurality
of printers (parallel print), a state in which a job allocated to
another printer is re-allocated to this printer because of a
defective condition of the other printer (deputy print).
[0126] The block of each printer is provided with a printer state
display area 1407 showing a state of the printer. In the area, a
current state of the printer is displayed with a predetermined
icon. FIG. 17 is an explanatory view showing a corresponding
relation between a printer state icon and a printer state.
[0127] Explanation of meaning of each state is omitted, but only
"STOP" will be explained. The "STOP" icon is displayed when a job
which is designated to be stopped comes, and when an operator stops
the operation of a printer by means of an operation panel or a
print server of the printer. This is different from giving a stop
attribute to the job, and directly gives stop instructions to the
printer.
[0128] FIG. 18 is an explanatory view showing a screen state (a
portion thereof) when the printer state icon is changed from
"READY" to "STOP". A stopped job 1801 moves toward the starting
point on the scale as time elapses, and its tip end coincides with
the starting point, the printer state icon is renewed to the lower
"STOP" to the upper "READY". When the tip end coincided with the
starting point, the processing time of the job approached.
[0129] A job which is being processed includes a job which is being
printed of course, and a job causing error during the printing
operation, and a job which is stopped by stopping instructions
although the printing time has come. More intuitively, the job
which is being processed is a job located at the top of the job
graph of each printer.
[0130] In FIG. 14, in-process job information display area 1406 (a
portion thereof) and the printer state display area 1407 of
"Printer A1" are surrounded by navy blue two dot frame line 1411,
and this indicates that this printer is currently selected (the
"selected printer" is different from "selected group"). It is
possible to instruct the selected printer to stop or restart from
upper icon and the like of the window.
[0131] Jobs which are not allocated to any of the printers are
arranged in the input order and displayed in the job graph display
area 1405 in the unallocated job display area 1402. Like the
allocated jobs, a length of the rectangular shape indicates
printing time calculated for the job, color or pattern of the
rectangular shape indicates a current state of the job (more
specifically, a state in which the job is not allocated to a
printer), and a length of the job graph indicates total time
required for processing all the unallocated jobs.
[0132] In the unallocated job display area 1402, there are provided
an all-unallocated job information display area 1408 for displaying
the total number of unallocated jobs and a total number of prints,
and a selected job information display area 1409 for displaying
name of document, user's name and memo (comment) of unallocated
job.
[0133] In order to allocate an unallocated job to any of the
printers, a selection instructions of a job and allocation
instructions to the job's printer are input from the inputting
section 305. More specifically, a jot to be allocated to a printer
is clicked by the mouse 212 first. The job selected in this manner
is highlighted and displayed with navy blue one dot frame line
1412.
[0134] Next, "printer allocation" is selected and executed from the
upper pull-down menu of the window. When the printer allocation was
executed from the menu in this manner, the printer allocating
section 307 which received instructions from the inputting section
305 adds, in principle, a selected job to the last of print-waiting
line of printers which has lowest load, i.e., which can start the
job fastest at this point in time.
[0135] However, when it is not desired to allow a printer capable
of starting the job fastest to do so, but when it is necessary to
allow a particular printer to do the job before a particular job,
the job can be put between desired jobs of a desired printer by
clicking the job to drag and drop as it is.
[0136] A boundary between jobs is clear by the one dot gap as
described above. In order to clearly show which side of the
boundary the job is put at the time of drag and drop of the job, an
interruption position pointers 1901 as shown in FIG. 19 on the gap
nearest the mouse cursor in principle. As the mouse cursor moves,
the pointers also move.
[0137] Each job is previously provided with precedence, a job can
interrupt when the job has the same or higher precedence as or than
that of an interrupted job. Therefore, the interruption position
pointer 1901 is not displayed in the gap when there is any job
having higher precedence behind a gap nearest the mouse cursor and
interruption of job having lower precedence is prohibited. In this
case, a job nearest the mouse cursor is selected from jobs in the
boundary which can be interrupted, and the interruption position
pointer 1901 is displayed in that position.
[0138] When a job interrupted by drag and drop, the printer
allocating section 307 which was informed by the inputting section
305 requests the printing time calculating section 306 to
re-calculate the printing time of the selected job using the
printing speed of the interrupting printer. Then, the printer
allocating section 307 requests the database managing section 303
to write the printer slated to process the job as the interrupting
printer, and the printing time as the printing time in the print
schedule table 303b.
[0139] The Web interface 301, the document managing server
interface 302, the database managing section 303, the printer
interface 304, the inputting section 305, the printing time
calculating section 306, the printer allocating section 307, the
main view display section 308 and the schedule view display section
309 realize functions thereof if the CPU 201 executes the
instructed processing in accordance with instructions described in
program stored in the storage medium such as the ROM 202, the RAM
203, the HD 205 or FD 207.
[0140] Next, procedure of display processing of schedule view of
the printer controlling device (print server 105) according to the
embodiment of the present invention will be explained. FIG. 20 is a
flowchart showing procedure of schedule view display processing of
the print server 105 of the embodiment of the invention. When the
schedule view icon 1204 was pushed on the main view shown in FIG.
12, the processing of this flowchart is started.
[0141] In step S2001, the job graph display section 309a of the
schedule view display section 309 requests the database managing
section 303 to retrieve all jobs slated to be completed after the
current date and time in each printer in the selected group.
[0142] In step S2002, lengths of the rectangular shapes showing
respective jobs are calculated from the printing time of jobs held
by the print schedule table 303b. For example, when 1 minute on the
scale is 4 dots and the printing time of the job is 120 minutes,
calculation is carried out in the following manner: 4
dots.times.120 minutes-1 dot of gap=479 dots. If this equation is
used, when the screen is enlarged, the gap of the job is also
enlarged, and it is possible to avoid a problem that outer
appearance is inferior.
[0143] From the state of each job held by the print schedule table
303b, color or pattern of the rectangular shape showing the job is
determined. Referring to the job ID, if there are small jobs
divided from the same parent job, these small jobs are provided
with the same characters. A rectangular image showing each job is
formed from the length, the color or the pattern, and the
character.
[0144] In step S2003, images of the jobs formed in step S2002 are
connected to each other through a distance of one dot for each
allocated printer, thereby forming an image of the job graph for
each printer.
[0145] In step S2004, the time scale display section 309b of the
schedule view display section 309 reads out an image of the
previously held time scale from a storage section (not shown).
[0146] In step S2005, the guide bar display section 309c of the
schedule view display section 309 judges whether the guide bar 1410
is set or not from a table (not shown) held in the guide bar
display section 309c. If the guide bar 1410 is set, its setting
date and time held in the above table and its setting position on
the scale are readout. Then, a new display position on the scale is
calculated based on the elapsed time from the setting date and time
to the current date and time.
[0147] For example, if the "guide bar display" is selected from the
"display" menu and the guide bar 1410 displayed in an arbitrary
position was moved to a position after 60 minutes on the scale at
11:00, and the current time is 11:10, the elapsed time (10 minutes)
from the setting date and time is subtracted the setting position
(after 60 minuets), and a new display position is calculated as
"after 50 minuets".
[0148] In step S2006, the in-process job information display
section 309d of the schedule view display section 309 requests the
database managing section 303 to read out a name of document, a
user's name, a memo, a job ID, a the number of copies, the number
of printing pages and the output form of a job which are being
processed from the print-job table 303a. The read out number of
copies is multiplied by the number of printing pages to obtain the
total number of prints which are being processed.
[0149] In step S2007, the printer state display section 309e of the
schedule view display section 309 requests the database managing
section 303 to read out a state of each printer in the selected
group from the printer table 303c. Images of icons corresponding to
the read out states are read out from the storage section (not
shown).
[0150] In step S2008, the job graph display section 309a of the
schedule view display section 309 requests the database managing
section 303 to retrieve all the jobs which are not allocated to the
printers from the print schedule table 303b. Then, in step S2009,
length, color or pattern of the rectangular shape showing each job
are determined from the printing time and the state in the print
schedule table 303b, thereby forming the image.
[0151] Further, in step S2010, the order of the rectangular shapes
formed in step S2009 is determined in accordance with the input
date and time of each job held in the print-job table 303a, and the
rectangular shapes are connected in this order at a distance of one
dot, thereby forming an image of the job graph of the unallocated
job.
[0152] In step S2011, the all-unallocated job information display
section 309f of the schedule view display section 309 counts the
total number of unallocated jobs retrieved in step S2008, and
requests the database managing section 303 to read out the number
of copies and the number of printing pages from the print-job table
303a. Then, the number of prints (=the number of copies.times.the
number of printing pages) of each job is accumulated to calculate
out the total number of prints of the unallocated jobs.
[0153] In step S2012, if there is a selected unallocated job among
the unallocated jobs, the selected job information display section
309g of the schedule view display section 309 requests the database
managing section 303 to read out a name of document, a user's name
and a memo from the print-job table 303a.
[0154] In step S2013, each of the above sections inserts the images
formed in the above steps, readout character information, the
calculated numerical values and the like into a previously prepared
image of the schedule view to show them on the screen. Thereafter,
the processing of this flowchart is completed.
[0155] As explained above, according to this embodiment, since
loads of the printers are displayed graphically by the job graph,
it is possible to intuitively grasp whether the loads are
appropriately distributed to the printers. Further, since the scale
is also displayed, it is possible to grasp not only the absolute
value of the load of each printer, but also the absolute amount
(absolute amount converted into the printing time).
[0156] Further, since each the rectangular shape in the job graph
shows the state of job by color or pattern of the rectangular
shape, it is possible to intuitively grasp the size, the state of
the input job, and the order of the jobs. Further, it is easy to
find when a particular job is processed by the scale and thus, it
is easy to manage the deadline of the jobs.
[0157] The total amount of the current jobs of each printer, the
total amount of unallocated jobs, the current states of each job
and each printer, jobs which are currently being processed, and the
details of the selected job are displayed easily for an operator in
real time. Therefore, it is possible to grasp current and future
operating status of the entire system at a glance.
[0158] The printer controlling method explained in the above
embodiment is realized by storing the program in a
computer-readable storage medium such a ROM, a HD, a FD, a CD-ROM,
an MO, a DVD, an IC card, and by reading out the program from the
medium by a computer. This program can be distributed as a transfer
medium through the above storage medium or through a network such
as Internet.
[0159] As explained above, according to the printer controlling
device and printer controlling method of the present invention, an
accumulation state of a job to each printer is displayed in a form
of the job graph comprising all jobs accumulated in the printer.
Therefore, there is an effect that it is possible to obtain a
printer controlling device capable of displaying load states of the
printers in an easy-to-understand manner graphically.
[0160] Furthermore, the accumulation state of each printer
belonging to the same group is displayed in the form of the job
graph comprising all jobs accumulated in the printer. Therefore,
there is an effect that it is possible to obtain a printer
controlling device capable of displaying the load state of the
printers in a group in the easy-to-understand manner
graphically.
[0161] Moreover, the accumulation state of a latest job to each
printer is always reflected to the job graph. Therefore, there is
an effect that it is possible to obtain a printer controlling
device capable of displaying the load state of the printers at
various time in the easy-to-understand manner graphically and in
real time.
[0162] Furthermore, the state of job in the job graph is displayed
with color or pattern of corresponding predetermined shape.
Therefore, there is an effect that it is possible to obtain a
printer controlling device capable of displaying the states of jobs
accumulated in the printers in the easy-to-understand manner
graphically and in real time.
[0163] Moreover, the same characters of a corresponding
predetermined shape is disposed in each job which as divided and
distributed by a parallel printing function. Therefore, there is an
effect that it is possible to obtain a printer controlling device
capable of displaying the relation of the plurality of jobs
processed by the plurality of printers in the easy-to-understand
manner.
[0164] Furthermore, a job amount and the entire amount accumulated
in each printer is displayed with an absolute amount converted into
the printing time. Therefore, there is an effect that it is
possible to obtain a printer controlling device capable of
converting the load states of the printers into the printing time
and displaying the same in the easy-to-understand manner.
[0165] Moreover, the guide bar capable of being used for various
purposes such as averaging of load states of the printers.
Therefore, there is an effect that it is possible to obtain a
printer controlling device capable of easily averaging the load
states of the printers.
[0166] Furthermore, the guide bar moves in an opposite direction on
the scale by an amount corresponding to the elapsed time.
Therefore, there is an effect that it is possible to obtain a
printer controlling device capable of easily grasping the remaining
time to achieve a target.
[0167] Moreover, detailed information of the job which is being
processed by a printer is displayed in addition to the accumulation
state of the job to the printer. Therefore, there is an effect that
it is possible to obtain a printer controlling device capable of
displaying, in the easy-to-understand manner, which the currently
processed job is.
[0168] Furthermore, detailed information of the job which is being
processed by each printer, i.e., at least one of the name of
document, the user's name, the memo, the job ID, the progress state
and the output form is displayed in addition to the accumulation
state of the job to the printer. Therefore, there is an effect that
it is possible to obtain a printer controlling device capable of
displaying the load state of the printers in the easy-to-understand
manner graphically, and which the currently processed job is.
[0169] Moreover, the accumulation state of the job to the printer
and detailed information of the job which is being processed by the
printer are displayed side-by-side. Therefore, there is an effect
that it is possible to obtain a printer controlling device capable
of collectively displaying the accumulation state of the job to the
printer and the detailed information of the job processed by the
printer in one place.
[0170] Furthermore, it is clearly indicated by the icon that a stop
of a printer is not due to trouble but due to suspending job.
Therefore, there is an effect that it is possible to obtain a
printer controlling device capable of displaying a cause of
suspension of a printer in the easy-to-understand manner.
[0171] Moreover, the accumulation state of a job which is not yet
allocated to a printer is displayed in a form of the job graph
comprising all unallocated jobs. Therefore, there is an effect that
it is possible to obtain a printer controlling device capable of
displaying the total amount of jobs which are not allocated to the
printer in the easy-to-understand manner graphically.
[0172] Furthermore, the total number of unallocated jobs and the
total number of prints are clearly indicated by means of numerical
values in addition to the job graph. Therefore, there is an effect
that it is possible to obtain a printer controlling device capable
of displaying the total amount of jobs which are not yet allocated
to the printers in the easy-to-understand manner, and displaying
with strict numerical value with the total number and the total
number of prints.
[0173] Moreover, the accumulation state of the unallocated jobs,
its total number and the total number of prints are displayed
side-by-side. Therefore, there is an effect that it is possible to
obtain a printer controlling device capable of collectively
displaying the accumulation state of the unallocated jobs and the
total number and the total number of prints in one place.
[0174] Furthermore, detailed information of a selected job among
the unallocated jobs is displayed together with the job graph.
Therefore, there is an effect that it is possible to obtain a
printer controlling device capable of displaying the total amount
of jobs which are not yet allocated to the printers in the
easy-to-understand manner graphically, and displaying which the
currently selected job is.
[0175] Moreover, detailed information of the selected job among the
unallocated jobs, i.e., at least one of the name of document, the
user's name, the memo, is displayed in addition to the job graph.
Therefore, there is an effect that it is possible to obtain a
printer controlling device capable of displaying the total amount
of jobs which are not yet allocated to the printers in the
easy-to-understand manner graphically, and displaying which the
currently selected job is.
[0176] Furthermore, the accumulation state of the unallocated job
and detailed information of the selected job are displayed
side-by-side. Therefore, there is an effect that it is possible to
obtain a printer controlling device capable of collectively
displaying the accumulation state of the unallocated jobs and
detailed information of the selected job in one place.
[0177] In addition, the interruption position pointer clearly
indicates which selected job interrupts between which jobs.
Therefore, there is an effect that it is possible to obtain a
printer controlling device capable of displaying the interruption
position of the selected job in the easy-to-understand manner.
