Exemplary embodiments of the present invention will be described in detail based on the following figures, wherein:
Exemplary embodiments according to the present invention will be described in detail with reference to the accompanying drawings.
The image forming system shown in
The image forming apparatus 100 shown in
The image forming section 10 is an image forming unit having four image forming units 11 (11Y, 11M, 11C, 11K for respective colors) in correspondence with the respective colors of yellow (Y), magenta (M), cyan (C) and black (K). Furthermore, the image forming section 10 includes a transporting belt 16 for transporting paper (print medium) as a target onto which toner images of the respective colors formed on respective photoconductor drums 12 of the respective image forming units 11 are transferred and multiplexed, a driving roll 17 for driving the transporting belt 16, a transfer roll for transferring the toner image formed on each photoconductor drum 12 onto paper (sheet), and a fixing unit 19 for heating and pressurizing a non-fixed toner image of the paper after the transfer. In this exemplary embodiment, the printing system of the image forming section 10 is not limited to a specific one. That is, the printing system of the image forming section 10 of this exemplary embodiment is not limited to an electrophotographic system shown in
The controller 20 is implemented by CPU, ROM for storing programs executed by CPU, RAM as a working memory, etc. The controller 20 controls the operation of the image forming section 10 and also controls various operations on the basis of pre-installed programs and various kinds of settings. Furthermore, the controller 20 accepts a print job from the print server 200, generates an image as a print target and executes various kinds of image processing such as change, correction, etc. of image size and layout.
The print server 200 and the client terminal 300 are implemented by a computer such as a personal computer or the like, for example.
The computer 310 shown in

Referring to
The job managing unit 201 generates managing information concerning a print job received from the client terminal 300 (hereinafter referred to as job managing information), and stores the print job into the data memory 202 to manage the print job. The job managing unit 201 successively transmits the print job to the image forming apparatus 100 on the basis of the job managing information and makes the image forming apparatus 100 execute the transmitted print job. That is, the job managing unit 201 is an example of a managing unit for managing print jobs, and also an example of an execution control unit for controlling execution of the print jobs.
When plural common print jobs contains a print condition (print setting), the job managing unit 201 links these print jobs, and makes the image forming apparatus 100 execute these print jobs as a single print job. Specifically, the job managing unit 201 registers print jobs received from the client terminal 300 as a unit called as “link job” into the job managing information and manages these print jobs. The link job is a virtually set job so that the print jobs are packaged and handled. The job managing unit 201 registers plural print jobs having the same print condition as print jobs constituting the same link job into the job managing information. Accordingly, there is a case where the link job is constructed by one print job or a case where the link job is constructed by plural print jobs. This link job is handed as an execution unit by the image forming apparatus 100. That is, the execution of print jobs in the image forming apparatus 100 is executed on a link-job basis. In other words, the image forming apparatus 100 executes the image forming processing while handling a link job (linked print jobs) as a single print job. Accordingly, the start-up processing and the stop processing are executed every time one link job is executed, and a print condition identified when print jobs are linked is obtained from a control command contained in the print jobs, for example.
The display controller 203 generates a status report for reporting an execution status of a print job on the basis of job managing information generated by the job managing unit 201, and displays the status report on the display device 210. The execution status of each print job issued from the client terminal 300 is displayed on the status report. As described above, there is a case where plural print jobs are converted to one (single) link job by the job managing unit 201. This conversion is executed in the internal processing of the print server 200, and thus this does not reflect the status report. That is, each print job issued from the client terminal 300 is individually described and the execution status thereof is displayed in the status report irrespective of whether print jobs are converted to a link job or not.
Managing items such as “job name”, “job ID”, “page number”, “output page number”, “status”, “link job” and “total page number of finished jobs” are set in the job managing information shown in
The item “job name” represents the name of a print job transmitted from the client terminal 300. The link job is created by the job managing unit 201 of the print server 200, and thus the job managing unit 201 provides the link job. In the example of
The item “Job ID” is managing information which is uniquely allocated when each job (link jobs and print jobs) is registered in the job managing information. In the example of
The item “page number” represents the number of pages of each job. In the case of a link job, the item “page number” represents the total number of pages of respective print jobs constituting the link job.
The item “output page number” represents the number of pages on which the processing has been executed. When “output page number” is equal to “page number”, it is determined that the job is finished.
The item “status” represents the status of each job. At the time point when a job is registered in the job managing information, “status” is set to “under processing”. When a cancel instruction is accepted, “status” is set to “during cancel”. However, there is no state of “finish”, and when execution of a job is finished, the job is deleted from the job managing information.
The item “link job” is identification information representing a discrimination between “link job” or “print job”. The item “total page number of finished jobs” represents the total number of pages of processing-completed print jobs out of the print jobs contained in a link job.
The status report shown in
As shown in
On the other hand, in step 702, when one or more link jobs are registered in the job managing information, the job managing unit 201 determines whether the print condition of the last link job out of the link jobs registered in the job managing information is identical to the print condition of the received print job (step 705). When these print conditions are identical to each other, the received print job is received as a print job constituting the last link job (in association with the last job) into the job managing information (step 706). Accordingly, the received print job is linked to the other print jobs constituting the last link job.
IN step 705, when the print condition of the last link job out of the link jobs registered in the job managing information is not identical to the print condition of the received print job, the job managing unit 201 creates a link job and registers the link job into the job managing information (step 703), and also registers the received print job as a print job constituting the created link job (in association with the created job) into the job managing information (step 704).
Next, the update processing of the job managing information and the status report in connection with execution of a print job (link job) will be described.
The job managing unit 201 successively transmits the jobs (link jobs and print jobs) registered in the job managing information as described above to the image forming apparatus 100 from the head job on a link-job basis, and makes the image forming apparatus 100 execute the transmitted job. Even during execution of a link job in the image forming apparatus 100, when the job managing unit 201 receives a new print job, the job managing unit 201 registers the received print job into the job managing information according to the procedure described with reference to
The image forming apparatus 100 transmits a notification indicating output completion of output pages to the job managing unit 201. On the basis of the information from the image forming apparatus 100, the job managing unit 201 updates the corresponding link job of the job managing information and the number of output pages in an entry of the head print job belonging to the link job. When the value of the output page number is equal to the value of the page number of the head print job belonging to the link job, it means that the processing of the print job is completed. Accordingly, the value of the total page number of the finished jobs in the entry of the link job is incremented by one, and the entry of the head print job for which the processing is completed is deleted.
Here, it is considered that the print server 200 receives a cancel command of the print job belonging to a link job while the link job is being executed in the image forming apparatus 100. When the print job as a cancel target has been already executed, it is needless to say that the execution of the print job is not ceased.
On the other hand, when the print job as a cancel target has not yet been executed, execution of the print job is canceled. In this exemplary embodiment, a print job is executed on a link-job basis, and thus cancellation of some print job affects execution of other print jobs which belong to the same link job and have not yet been executed. Specifically, when execution of some print job is cancelled, execution of other print jobs which belong to the same link job and are registered after the canceled print job (that is, which are going to be executed after the cancelled print job) is canceled. However, plural print jobs constituting a link job are print jobs which are originally individually issued, and thus even when execution of some of the print jobs is canceled, the other print jobs must be executed.
Therefore, in order to execute non-executed print jobs (hereinafter referred to as “non-executed job”) which belong to the same link job as the cancel target print job and registered after the cancel target print job (hereinafter referred to as “target job”), the job managing unit 201 itself re-issues a print job as a non-executed job. Specifically, the job managing unit 201 transmits a print job while setting the job managing unit 201 as a transmission destination. At this time, in order to discriminate the print job re-issued by the job managing unit 201 itself from a normal print job issued by the client terminal 300, the re-issued print job is transmitted with being added with a job ID in the job managing information. On the basis of whether the received print job is added with a job ID or not, the job managing unit 201 identifies whether the print job is the print job re-issued by the job managing unit 201 itself.
Furthermore, in this exemplary embodiment, with respect to the job managing information, in order to discriminate re-issued print jobs and a link job containing the re-issued print jobs from other normal print jobs and a link job containing the normal print jobs, two statuses of “wait for restart” and “under processing (2)” are newly introduced in the status.
“Wait for restart” is used for the entry of a link job in the job managing information. This status represents a waiting state for restart of execution of non-executed jobs when some of print jobs belonging to a link job are canceled and non-executed jobs which are not canceled exist. When the execution of the non-executed jobs is restarted, the status of the link job is shifted from “wait for restart” to “under processing”.
“Under processing (2)” is used for the entry of a print job in the job managing information. This status represents a waiting state for restart of execution based on re-issue of a print job when other print jobs belonging to the same link job are canceled. When execution of a print job is restarted, the status of the print job is shifted from “under processing (2)” to “under processing”. This status “under processing (2)” is used in the status report.
When receiving a print job having a job ID as described above, the job managing unit 201 of this exemplary embodiment does not newly register the received print job in the job managing information, but registers the received print job by overwriting the received print job on the entry of the corresponding non-executed job whose status is “under processing (2)”. On the basis of the re-registered print job, execution of the link job containing this print job is restarted.
As shown in
When the target job has not yet been executed, the job managing unit 201 executes a cancel instruction of the target job to the image forming apparatus 100 (step 804). At this time, when a non-executed job (a print job which belongs to the same link job as the target job and registered after the target job) exists, the cancel instruction is also executed on the non-executed job. The job managing unit 201 sets the status of the target job in the job managing information to “during cancel”. In connection with this operation, the display controller 203 sets the status of the target job in the status report to “during cancel” (step 805).
When the execution of print jobs progresses and the canceled print job (target job) is set to the head of the link job (step 806), the job managing unit 201 deletes the entry of the target job from the job managing information. Accordingly, the print jobs contained in the link job to which the target job belongs include only non-executed jobs. Furthermore, the status of the link job is set to “wait for restart”, and the status of the non-executed job is set to “under processing (2)” (step 807). The job managing unit 201 instructs the image forming apparatus 100 to finish the execution of jobs (step 808), and in response to this instruction, the image forming apparatus 100 executes the stop processing. Accordingly, the execution of the link job is finished, and thus all of the page number, the output page number and the total page number of the finished jobs are set to “0” in the entry of the link job in the job managing information. The entries of the link jobs and the non-executed jobs are not deleted from the job managing information. Thereafter, the job managing unit 201 executes the restart processing to execute the non-executed jobs (step 809).
The job managing unit 201 first executes a job starting instruction (step 901). In response to this instruction, the image forming apparatus 100 executes the start-up processing. Furthermore, the job managing unit 201 transmits a print job added with a job ID with respect to the non-executed jobs while setting the print server 200 as a transmission destination (step 902). When a fixed time which is preset to receive the print job added with the job ID elapses after transmission of the print job with the job ID in step 902, the job managing unit 201 deletes the entry in which the status of the job managing information is set to “under processing (2)”.
Subsequently, when receiving the print job with the job ID within the fixed time described above (step 903), the job managing unit 201 checks whether the received print job with the job ID is registered in the job managing information (step 904). When the received print job with the job ID is registered in the job managing information, the job managing unit 201 overwrites the print job with the job ID on the job managing information to register the print job, and changes the status to “under processing” (step 905).
Subsequently, with respect to a link job in which the status in the job managing information is set to “wait for restart”, the job managing unit 201 determines whether the status of the non-executed job at the head of the non-executed jobs belonging to the link job is set to “under processing” or not (step 906). When the status of the head non-executed job in the link job is not set to “under processing” (that is, in the case of “under processing (2)”), the job managing unit 201 returns to the step 903 to wait for reception of a print job with a job ID until the fixed time elapses.
When the status of the head non-executed job in the link job is set to “under processing”, the job managing unit 201 changes the status of the job managing information of the link job to “under processing” (step 907). Accordingly, the execution of this link job by the image forming apparatus 100 is restarted. The status of the head non-executed job of the link job is set to “under processing” in the following cases. That is, the print job added with the job ID corresponding to the head non-executed job is received. Furthermore, the entry of the non-executed job in which the status in the job managing information is set to “under processing (2) ” is deleted because the fixed time elapses from the transmission of the print job added with the job ID in step 902, so that a non-executed job whose print job with the job ID is received is set to the head print job.
Here, there is a case where a print job with a job ID is received, however, the received print job with the job ID is not registered in the job managing information (“No” in step 904). For example, there is a case where after the entry of a non-executed job in which the statue in the job managing information is set to “under processing (2) ” is deleted because the fixed time elapses from transmission of a print job with a job ID in step 902, the print job with the job ID corresponding to the deleted entry is received. In this case, the job managing unit 201 transmits to the client terminal 300 a notification indicating that the received print job with the job ID cannot be executed (error response), and then finishes the processing (step 908). When the print job with the job ID cannot be overwritten and registered in the job managing information, a new job ID may be newly provided so that the print job is executed as a normal print job without error-finishing the processing as described above.
The updating operation of the job managing information and the status report will be further described with reference to
First, it is assumed that the print server 200 receives a print job “Job1” from the client terminal 300 after the job managing information and the status report are initialized. At this time, the job managing unit 201 generates a link job “renJob1”, and registers “renJob1” and “Job1” into the job managing information. On the basis of this job managing information, the information of “Job1” is displayed in the status report.
Next, it is assumed that the job managing unit 201 receives a print job “Job2” having the same print condition as “Job1”. Since “Job2” has the same print condition as “renJob1” (=“Job1”), the print job “Job2” is registered as a print job belonging to the same “renJob1” as “Job1” into the job managing information.
Next, it is assumed that the job managing unit 201 receives print jobs “Job3” to “Job6” having the same print condition as “renJob1”. The print jobs “Job3” to “Job6” are registered as print jobs belonging to “renJob1” into the job managing information because they have the same print condition as “renJob1”.
Next, it is assumed that the job managing unit 201 receives an output completion notification of the first page from the image forming apparatus 100. In response to this notification, the job managing unit 201 sets the output page numbers of “renJob1” and “Job1” of the job managing information to 1.
Here, the page number of “Job1” is equal to 1, and the output of the first page of “renJob1” is completed, so that the execution of “Job1” is finished. This is recognized by the fact that the page number of “Job1” is equal to the output page number (in this case, “1”). Therefore, the job managing unit 201 sets the total page number of the finished job of “renJob1” to 1 (the number of pages of the finished “Job1”), and deletes the entry of “Job1” from the job managing information. In connection with this deletion, the display controller 203 also deletes the entry of “Job1” from the status report.
Next, it is assumed that the job managing unit 201 receives a cancel command of “Job3” and “Job5” from the client terminal 300 and also receives an output completion notification of the second page from the image forming apparatus 100. In response to this notification, the job managing unit 201 sets the output page number of “renJob1” of the job managing information to 2, and sets the output page number of “Job2” to 1. Furthermore, the job managing unit 201 changes the statuses of “Job3” and “Job5” to “under cancel”. The display controller 203 sets the output page number of “Job2” in the status report to 1, and changes the statuses of “Job3” and “Job5” to “under cancel”.
Next, it is assumed that the job managing unit 201 receives an output completion notification of the third page as the last page which is not canceled. In connection with this notification, the job managing unit 201 sets the output page number of “renJob1” of the job managing information to 3, and sets the output page number of “Job2” to 2.
Here, since the page number of “Job2” is equal to 2, the number of pages (the value of the page number) of “Job2” is equal to the number of output pages (the value of the output page number) (in this case, “2”), and thus the execution of “Job2” is finished. Therefore, the job managing unit 201 sets the total page number of the finished jobs of “renJob1” to 3 (the page number 2 of the finished “Job2” is added to the original page number 1), and deletes the entry of “Job2” from the job managing information. In connection with this deletion, the display controller 203 also deletes the entry of “Job2” from the status report.
Referring to
Subsequently, the processing is shifted to the restart processing shown in
The job managing unit 201 first transmits the print job with the job ID of each of “Job4” and “Job6” to the print server 200. It is assumed that the print job with the job ID of “Job6” is received. At this time, there exists an entry of “Job6” in which the status of the job managing information is set to “under processing (2)”, and thus the job managing unit 201 overwrites and registers the received print job with the job ID on this entry, and changes the status to “under processing”. Furthermore, since “Job6” is re-registered, the page number of “renJob1” is set to “6” (the page number of “Job6”).
Next, it is assumed that after the job managing unit 201 transmits the print jobs with the job IDs of “Job4” and “Job6”, a fixed time set to receive the print job with the job ID elapses without receiving the print job with the job ID of “Job4”. In this case, the job managing unit 201 deletes from the job managing information the entry of “Job4” whose status is “under processing (2)”.
Here, the status of the head non-executed job (“Job6”) belonging to “renJob1” is set to “under processing” because the entry of “Job4” is deleted. Therefore, the job managing unit 201 changes the status of “renJob1” in the job managing information to “under processing” as represented by the steps 906 and 907 of
Thereafter, when the job managing unit 201 receives an output completion notification of six pages as the data of “Job6” from the image forming apparatus 100, the page number of “Job6” is equal to the output page number (in this case, “6”), and the execution of “Job6” is finished. Furthermore, the values of the page number, the output page number and the total page number of the finished jobs of “renJob1” are equal to one another (in this case, “6” because the page number is equal to the page number of “Job6”), and the execution of “renJob1” is finished. Accordingly, the job managing unit 201 deletes the entries of “renJob1” and “Job6” from the job managing information. In connection with this deletion, the display controller 203 deletes the entry of “Job6” from the status report.
Here, it is assumed that after the entry of “Job4” is deleted from the job managing information, the job managing unit 201 receives the print job with the job ID of “Job4”. However, the entry of “Job4” in the job managing information has been already deleted, and thus it cannot be overwritten and registered as a print job belonging to “renJob1”, so that the processing of “Job4” is error-finished. In this case, as described above, “Job4” may be processed as in the case of a normal print job received from the client terminal 300 without error-finishing the processing of “Job4”. That is, “renJob2” constructed by “Job4” may be generated, and “renJob2” and “Job4” may be newly registered in the job managing information to control the management and execution of “Job4”.
As described above, according to the image forming system in which plural print jobs are executed while linked to each other, when a cancel command is issued to some of print jobs belonging to a link job, the other print jobs belonging to the same link job are cancelled together although no cancel instruction is issued to these print jobs. However, according to this exemplary embodiment, in order to execute the other print jobs as described above, the print job with the job ID issued by the print server 200 and the two statuses of “wait for restart” and “under processing (2)” in the status of the job managing information are introduced.
On the other hand, according to a second exemplary embodiment, the other print jobs belonging to the link job containing the print job to which the cancel command is issued are temporarily stored in a second queue which is prepared in addition to a queue for holding a print job to execute the print job, whereby the other print jobs can be executed. In only the status report, “under processing (2)” representing a restart waiting status is displayed in the status.
Referring to
The job managing unit 221 generates managing information concerning a print job received from the client terminal 300 (hereinafter referred to as “job managing information”), and stores the print job into the data memory 222 to manage the print job. The job managing unit 221 successively transmits the print job to the image forming apparatus 100 on the basis of the job managing information to execute the print job. Furthermore, when there are plural print jobs having the same print condition (print setting), the job managing unit 221 links these print jobs and makes the image forming apparatus 100 execute these print jobs as a single print job. Specifically, the job managing unit 221 registers the print jobs received from the client terminal 300 as an unit called as a link job to mange these print jobs. The respective functions of the job managing unit 221 are the same as the job managing unit 201 shown in
The data memory 222 stores the job managing unit generated by the job managing unit 221 and the print job received from the client terminal 300. Furthermore, two kinds of queues are prepared as a print job holding unit in the data memory 222. One kind of queue is an executing queue 222a used under a normal state, and the other kind of queue is a restart waiting queue 222b used to hold other print jobs (non-executed jobs) which are canceled because a cancel command is issued to some of print jobs contained in a link job.
The display controller 223 generates a status report for notifying an execution condition of a print job to a user on the basis of the job managing information generated by the job managing unit 221, and stores the status report into the status report managing information memory 224 to manage the status report. The status report stored in the status report managing information memory 224 is displayed on the display device 210. The configuration of the status report is the same as the status report shown in
Next, the update processing of the job managing information and the status report in the second exemplary embodiment will be described.
The processing of accepting a print job from the client terminal 300 and updating the job managing information by the job managing unit 221 and the processing of accepting a cancel command of a print job from the client terminal 300 and changing the status of the target job (the cancel target print job based on the accepted cancel command) to “under cancel” by the job managing unit 221 are the same as the first exemplary embodiment described with reference to
When there exists a non-executed print job which belongs to the same link job as the target job, registered after the target job and has not yet been executed and to which no cancel command is issued, the job managing unit 221 of this exemplary embodiment transfers this non-executed job from the executing queue 222a to the restart waiting queue 222b. Then, the job managing unit 221 deletes the entries of the link job and all the print jobs belonging to this link job (the target job and the non-executed jobs). Thereafter, the job managing unit 221 transfers the non-executed jobs form the restart waiting queue 222b to the executing queue 222a again, registers the non-executed jobs into the job managing information and makes the image forming apparatus 100 execute the non-executed print jobs.
The display controller 223 of this exemplary embodiment temporarily stores a status report created and updated on the basis of the job managing information into the status report managing information memory 224, read out the status report from the status report managing information memory 224 and displays the status report on the display device 210. When the non-executed job is transferred to the restart waiting queue 222b by the job managing unit 221, the display controller 223 sets the status of the entry of the non-executed job in the status report to “under processing (2)” representing the restart waiting state, and stops the update of the status report. When the non-executed job is returned to the executing queue 222a by the job managing unit 221 and registered into the job managing information again, the update of the status report is restarted on the basis of the job managing information.
In
In the job managing information and the status report, after the status of a target job is set to “under cancel”, execution of the print job progresses, and when the canceled print job (target job) is the head of the link job (step 2306), the job managing unit 221 transfers the non-executed job from the executing queue 222a to the restart waiting queue 222b. The job managing unit 221 notifies it to the display controller 223 that the non-executed job is set to “restart waiting state”, and deletes the target job and the entry of the non-executed job from the job managing information (step 2307).
When receiving the notification from the job managing unit 221, the display controller 223 sets the status of the entry of the non-executed job in the status report to “under processing (2)”, and stops the update of the status report (step 2308). Thereafter, the job managing unit 221 instructs the image forming apparatus 100 to finish the execution of the job (step 2309), and in response to this instruction, the image forming apparatus 100 executes the stop processing. Furthermore, the job managing unit 221 executes the restart processing to execute a non-executed job (step 2310).
The job managing unit 221 first checks whether a print job is held in the restart waiting queue 222b of the data memory 222 (step 2401). When no print job is held in the restart waiting queue 222b, it means that there does not exist any non-executed job when the execution of the print job is canceled, that is, all the print jobs except for the target job belonging to the link job have been executed, and thus the restart processing is finished.
On the other hand, when a print job is held in the restart waiting queue 222b, the job managing unit 221 returns this print job to the executing queue 222a, and registers the print job into the job managing information (step 2402). This registration is identical to the registration of a normal print job received from the client terminal 300. That is, a link job for the print job returned to the executing queue 222a is created, and this link job and print jobs belonging to the link job are registered in the job managing information.
The display controller 223 changes the status of the entry of the non-executed job in the status report to “under processing”, and restarts the update of the status report (step 2403). Thereafter, the job managing unit 221 instructs the image forming apparatus 100 to start execution of the job (step 2404). In response to this instruction, the image forming apparatus 100 executes the start-up processing, so that execution of a print job is started.
The update operation of the job managing information and the status report will be further described with reference to
First, it is assumed that the update of the job managing information and the status report progresses as in the case of
Under the state of
The display controller 223 receives this notification from the job managing unit 221, changes the statuses of “Job4” and “Job6” to “under processing (2)” as indicated by the step 2308 of
Subsequently, the processing is shifted to the restart processing shown in
The display controller 223 receives a notification from the job managing unit 221, and restarts the update of the status report as indicated by the step 2403 of
Subsequently the job managing unit 221 instructs the image forming apparatus 100 to start execution of jobs, and transmits the data of “Job4” and “Job6” as the data of first to tenth pages of “renJob2” to the image forming apparatus 100. The image forming apparatus 100 executes the start-up processing in response to the start instruction, and then executes “renJob2”.
Here, it is assumed that the image forming apparatus 100 completes the output of the first to fourth pages and the job managing unit 221 receives an output completion notification of the first to fourth pages. At this time, the page number of “Job4” is equal to four pages, and the page number of “Job4” is equal to the output page number (in this case, “4”), so that the execution of “Job4” is finished. Therefore, the job managing unit 221 sets the total page number of the finished jobs of “renJob2” to four (the page number of the finished “Job4”), and deletes the entry of “Job4” from the job managing information. In connection with this deletion, the display controller 223 also deletes the entry of “Job4” in the status report.
