Then, the job management unit 28 registers the calculated time in the scheduled execution start time 34 of the job management information 28a.

  The acquisition source 35 is information indicating the acquisition source of the print job. For example, when a print job is received from the computers 4a and 4b via the network 5, information indicating that the acquisition source of the print job is an external computer is registered in the acquisition source 35 column. On the other hand, when the document data DA is acquired from the document editing server 2 and a print job is registered, the acquisition source 35 field includes information indicating that the acquisition source of the print job is the document editing server 2. be registered. At this time, access information D5 for accessing the document editing server 2 may be registered in the acquisition source 35.

  The document information 36 is information registered when the print job registered in the print job storage unit 19 by the print job registration unit 24 is a job generated based on the document data DA acquired from the document editing server 2. is there. Registered in the document information 36 is information such as document ancillary information D7 included in the invitation mail D4 and data acquisition time required for acquiring the document data DA from the document editing server 2.

  In the job management information 28a shown in FIG. 5, a print job based on the document data DA acquired from the document editing server 2 is registered as the third job. Therefore, after the execution of the first and second print jobs is finished, the print job generated based on the document data DA is executed, and the state stored in the print job storage unit 19 until then is executed. This is a standby job that waits at

  Returning to FIG. 4, the job management unit 28 manages the print order of the print jobs stored in the print job storage unit 19 based on the job management information 28a as described above. A target print job is instructed to the job execution unit 29.

  The job execution unit 29 is a processing unit that reads a print job instructed by the job management unit 28 from the print job storage unit 19 and outputs the print job to the printer unit 14 for execution. When the job execution unit 29 outputs a print job to the printer unit 14, the printer unit 14 starts an operation of transferring and fixing a toner image onto a print sheet or the like based on the print job. Is printed out. In this way, the job execution unit 29 sequentially executes the print jobs stored in the print job storage unit 19 based on an instruction from the job management unit 28.

  When the job execution unit 29 finishes executing the print job, the job management unit 28 deletes information corresponding to the job from the job management information 28a. Therefore, in the job management information 28a, only the standby job stored in the print job storage unit 19 and in the standby state is managed. The job management unit 28 records and saves the information deleted from the job management information 28a in the job history information, which is not shown.

  When a print job based on the document data DA acquired from the document editing server 2 is registered as a standby job in the job management information 28a, the job management unit 28 as described above is executed by the job execution unit 29. The document editing server 2 confirms whether or not the document data DA has been updated at a predetermined timing before being performed. More specifically, the job management unit 28 activates the browser program 18 when it is time to confirm the update of the document data DA. Based on the access information D5, the document editing server 2 is automatically logged in to access the document data DA. Then, after the document data acquisition unit 25 acquires the document data DA, the job management unit 28 checks whether the document data DA held in the document editing server 2 has been updated. For example, the job management unit 28 obtains the document ancillary information D7 at that time from the document editing server 2, and if the update date / time or revision number of the document data DA is changed, the document data DA is updated. Judge that

  When the document data DA is updated, the job management unit 28 causes the document data acquisition unit 25 and the print job generation unit 26 described above to function again, and re-acquires the updated document data DA from the document editing server 2. At the same time, a print job is generated again based on the re-acquired document data DA. Then, the job management unit 28 acquires a print job generated based on the updated document data DA, and the print job generated based on the pre-updated document data DA already stored in the print job storage unit 19. Is replaced with a print job generated based on the updated document data DA. Thereby, when the print job generated based on the pre-update document data DA is executed by the job execution unit 29, the print job generated based on the post-update document data DA is read out. Will be executed.

  If the document data DA has been updated, the job management unit 28 updates the updated data for the user A who has instructed printing of the document data DA before starting reacquisition of the updated document data DA. An inquiry may be made as to whether or not the document data DA is reacquired. Various methods are conceivable as a method for making such an inquiry. For example, a method of sending an e-mail to the user A based on the user information 32 may be adopted, or the computer 4a of the user A may be used. Alternatively, a method of directly sending an inquiry notification may be employed.

  The job management unit 28 waits for a response from the user A to the inquiry until a predetermined time elapses. If there is a response from the user A until the predetermined time elapses, the job management unit 28 updates the document based on the response result. It is determined whether or not the data DA is reacquired. For example, if the response from the user A requests reacquisition, it is determined to reacquire the updated document data DA, and as described above, the document data acquisition unit 25 and the print job generation unit 26 Is made to function again to re-acquire the updated document data DA from the document editing server 2 and to generate a print job again based on the re-acquired document data DA. Then, the print job to be printed is replaced with a print job generated based on the updated document data DA. On the other hand, when the response from the user A does not request reacquisition, the re-acquisition of the updated document data DA is not performed.

  In this way, when the job management unit 28 makes an inquiry to the user A who has given the print instruction whether or not to re-acquire the updated document data DA, whether the document data DA is to be printed in the latest state. It is possible to confirm the intention of the user A about whether or not, and it is possible to perform a print output in accordance with the intention of the user A. However, after making an inquiry to the user A, the job management unit 28 determines to reacquire the updated document data DA when there is no response from the user A and a predetermined time has elapsed. It is preferable to replace the print job. As a result, the document data DA is printed out in the latest state.

  Note that, as a result of checking whether or not the document data DA held in the document editing server 2 has been updated, if the document data DA has not been updated, the document data DA needs to be reacquired. Therefore, the print job already stored in the print job storage unit 19 becomes an execution target as it is.

  The above-described replacement of the print job is preferably completed before the job execution unit 29 starts executing the print job generated based on the document data DA before update. For this reason, when a print job based on the document data DA acquired from the document editing server 2 is registered as a standby job, the job management unit 28 sets the scheduled execution start time of the print job and the required time for data acquisition to the job management information. It is configured to check whether or not the document data DA is updated in the document editing server 2 at a timing that is at least a time required for data acquisition from the scheduled execution start time.

  FIG. 6 is a diagram for explaining an example of the timing for confirming whether or not the document data DA is updated. In FIG. 6, for example, three print jobs “JOB1”, “JOB2”, and “JOB3” are sequentially executed in this order, and the document acquired from the document editing server 2 among these three print jobs. A case where the print job based on the data DA is “JOB3” is shown. In the example of FIG. 6, the scheduled execution start time of “JOB1” is T1, the scheduled execution start time of “JOB2” is T2, and the scheduled execution start time of “JOB3” is T3. Then, assuming that the required data acquisition time required to acquire the document data DA corresponding to “JOB3” is TG, the job management unit 28 has at least the required data acquisition time from the scheduled execution start time T3 of “JOB3”. The document editing server 2 is accessed at a timing Ta that is only TG before, and it is confirmed whether or not the document data DA has been updated.

  By confirming whether or not the document data DA has been updated at the timing Ta, when the document data DA has been updated, the re-acquisition of the updated document data DA is performed until the scheduled execution start time T3 of “JOB3” arrives. Will be able to do. Therefore, if the scheduled execution start time T3 arrives without delaying the execution start of “JOB3”, the execution of “JOB3” can be started with the replaced print job.

  Note that the timing at which the job management unit 28 confirms whether or not the document data DA is updated is not limited to the timing Ta shown in FIG. 6, and may be a timing before the timing Ta shown in FIG. 6. For example, as described above, after confirming that the document data DA has been updated, when inquiring whether to re-acquire the updated document data DA to the user A who has given the print instruction. Waits for a predetermined time until there is a response from the user A, so it is preferable to check whether or not the document data DA is updated at a timing that is earlier than the timing Ta shown in FIG. By doing so, even if the user A is inquired, the execution of the print job corresponding to “JOB3” is started when the scheduled execution start time T3 arrives without delaying the execution start of “JOB3”. Will be able to.

  Next, a specific processing procedure of the control unit 10 configured as described above will be described. 7 to 11 are flowcharts illustrating an example of a processing procedure performed in the control unit 10. First, as shown in FIG. 7, when this process is started, the control unit 10 determines whether or not an e-mail has been received (step S1). As a result, when an electronic mail is received (YES in step S1), the control unit 10 executes an electronic mail reception process (step S2). On the other hand, when no e-mail is received (NO in step S1), the e-mail receiving process is not performed.

  Next, the control unit 10 determines whether or not a print job has been generated (step S3). If no print job has been generated (NO in step S3), it is further determined whether a print job has been received via the network 5 (step S4). When the control unit 10 generates a print job (YES in step S3) or receives a print job via the network 5 (YES in step S4), the control unit 10 executes a print job registration process (step S5). . On the other hand, if no print job is generated (NO in step S3) and no print job is received via the network 5 (NO in step S4), the print job registration process is not performed.

  Next, the control unit 10 determines whether there is a waiting print job stored in the print job storage unit 19 (step S6). As a result, when there is a waiting print job (YES in step S6), the control unit 10 executes a job management process (step S7). Then, the control unit 10 determines whether or not it is the timing when the execution of the print job stored in the print job storage unit 19 can be started (step S8). Here, for example, it is confirmed whether or not the print job is being executed in the printer unit 14, and it is determined that the print job can be started when the print job is not executed in the printer unit 14. . If it is time to start execution of the print job (YES in step S8), the control unit 10 executes job execution start processing (step S9). On the other hand, if there is no waiting print job in step S6, the job management process (step S7) is not executed, and if it is not the timing at which execution of the print job can be started in step S8, Job execution start processing is not executed. And the control part 10 returns to step S1, and repeatedly performs the process mentioned above.

  FIG. 8 is a flowchart showing an example of a detailed processing procedure of the e-mail receiving process (step S2). When starting this process, the control unit 10 determines whether or not the received electronic mail is an invitation mail D4 transmitted from the document editing server 2 (step S10). If the received electronic mail is not the invitation mail D4 (NO in step S10), this process ends. However, processing corresponding to the received electronic mail may be performed. On the other hand, when the received electronic mail is the invitation mail D4 (YES in step S10), the control unit 10 extracts the access information D5 from the invitation mail D4 (step S11). At this time, the control unit 10 extracts not only the access information D5 but also the user information D6 and the document attached information D7 included in the invitation mail D4.

  Then, the control unit 10 activates the browser program 18 (step S12), accesses the document editing server 2 based on the access information D5 extracted in step S11, and automatically logs in (step S13). As a result, the control unit 10 can access the document data DA to be printed held in the document editing server 2 using the browser function realized by the browser program 18. Then, the control unit 10 starts downloading the document data DA to be printed from the document editing server 2 (step S14), and starts measuring the time required for the download acquisition (step S15). Thereafter, when the acquisition of the document data DA from the document editing server 2 is completed (step S16), the control unit 10 ends the time measurement operation (step S17), and acquires the time required for acquiring the document data DA. Memorize as time required.

  Then, the control unit 10 ends the activation of the browser program 18 (step S18), and generates a print job based on the document data DA acquired from the document editing server 2 (step S19). Thus, the e-mail reception process (step S2) is completed.

  FIG. 9 is a flowchart illustrating an example of a detailed processing procedure of the print job registration process (step S5). When the control unit 10 starts this process, the control unit 10 performs the print job generated by the above-described e-mail reception process (step S2) or the print job received from the other computers 4a and 4b via the network 5. A unique job ID is issued (step S20). The control unit 10 adds the job ID to the print job and saves it in the print job storage unit 19 (step S21). The control unit 10 registers information related to the print job in the job management information 28a (step S22). At this time, the control unit 10 calculates the scheduled execution start time of the print job, registers it in the job management information 28a, and the print job is a print job generated by the above-described e-mail reception process (step S2). In this case, information indicating the document editing server 2 is registered in the field of the acquisition source 35, and the document ancillary information D7 included in the invitation mail D4 and the document data DA are further registered in the field of the document information 36. Register information such as the data acquisition time required for acquisition. This completes the print job registration process (step S5).

  Next, FIG. 10 is a flowchart illustrating an example of a detailed processing procedure of the job management process (step S7). When starting this process, the control unit 10 reads the job management information 28a (step S30). Then, it is determined whether the print job acquired from the document editing server 2 is registered in the job management information 28a (step S31). As a result, if the print job acquired and generated from the document editing server 2 is not registered (NO in step S31), this process ends.

  On the other hand, when the print job acquired and generated from the document editing server 2 is registered (YES in step S31), the control unit 10 reads the scheduled execution start time of the print job (step S32), and further The data acquisition time is read (step S33). Then, the control unit 10 performs an operation based on the scheduled execution start time and the required data acquisition time, and determines whether or not the current timing is a timing for confirming whether or not the document data DA is updated (step S34). As a result, if it is not time to confirm whether or not the document data DA has been updated (NO in step S34), this process ends. On the other hand, when it is time to check whether or not the document data DA is updated (YES in step S34), the control unit 10 checks in the document editing server 2 whether or not the document data DA is updated in step S35. Proceed with the process.

  Then, the control unit 10 activates the browser program 18 (step S35), accesses the document editing server 2 based on the access information D5, and automatically logs in (step S36). Then, the control unit 10 confirms the document data DA held in the document editing server 2 (step S37), and determines whether or not the document data DA has been updated (step S38).

  As a result, when the document data DA has been updated (YES in step S38), the control unit 10 issues a reacquisition confirmation notification for inquiring reacquisition to the user A who has instructed printing of the document data DA. It transmits to the user A (step S39). Note that this reacquisition confirmation notification may be transmitted to the email address of the user A or directly to the computer 4a of the user A. Then, the control unit 10 waits until a response from the user A is obtained or until a predetermined time elapses, and then determines whether or not to reacquire the document data DA (step S40).

  When the document data DA is reacquired (YES in step S40), the control unit 10 reacquires the document data DA updated from the document editing server 2 (step S41), and the reacquired document data is acquired. A print job is generated based on DA (step S42). Then, the control unit 10 replaces the print job generated based on the document data DA before update with the print job generated based on the document data DA after update (step S43). This print job replacement is performed so that the execution order with other print jobs is not changed. Further, the replacement of the print job is performed until the scheduled execution start time of the print job generated based on the document data DA comes.

  On the other hand, if the document data DA has not been updated (NO in step S38), the above steps S39 to S43 are not performed and the process skips. If the user A does not request reacquisition of the document data DA (NO in step S40), the above steps S41 to S43 are not performed and the process skips. And the control part 10 complete | finishes starting of the browser program 18 (step S44), and complete | finishes this process. This completes the job management process (step S7).

  Next, FIG. 11 is a flowchart showing an example of a detailed processing procedure of the job execution start process (step S9). When starting this processing, the control unit 10 reads out a print job to be executed from the print job storage unit 19 (step S50), and outputs the read print job to the printer unit 14 (step S51). Then, the control unit 10 causes the printer unit 14 to start print output (step S52). Thereafter, the control unit 10 deletes information related to the print job output from the job management information 28a to the printer unit 14 and updates the job management information 28a (step S53). This completes the job execution start process (step S9).

  Therefore, the image forming apparatus 3 according to the present embodiment, as shown in FIG. 2, after receiving the invitation mail D4 from the document editing server 2 according to the print instruction D2 of the user A, as shown in FIGS. Operate. FIG. 12 is a diagram illustrating a flow of data communication in which the image forming apparatus 3 acquires the document data DA from the document editing server 2. After receiving the invitation mail D4 from the document editing server 2, the image forming apparatus 3 accesses the document editing server 2 based on the access information D5, and acquires the document data DA to be printed from the document editing server 2 (arrow) F3). Then, the image forming apparatus 3 generates a print job JD based on the document data DA and stores it in the print job storage unit 19.

  At this time, if other print jobs are stored in the print job storage unit 19 first, the image forming apparatus 3 waits until the execution of the other print jobs is completed. save. Even when another print job is already being executed at the timing when the print job JD is generated, the image forming apparatus 3 stores the print job JD as a standby job that waits until the print job being executed ends. To do. In such a case, it takes time until the print output of the document data DA acquired from the document editing server 2 is started.

  On the other hand, as described above, the document editing server 2 allows a plurality of users A, B, and C to simultaneously perform editing operations on the document data DA. For this reason, after the image forming apparatus 3 acquires the document data DA from the document editing server 2 and before the execution of the print job JD based on the document data DA is started, the other user B, for example, receives the document data DA. There is a possibility of updating to different contents (arrow F4).

  FIG. 13 is a diagram illustrating a flow of data communication when the scheduled print start time of the print job JD in the standby state in the image forming apparatus 3 is approaching. When the scheduled print start time of the print job JD based on the document data DA approaches, the image forming apparatus 3 accesses the document editing server 2 to check whether the document editing server 2 has been updated or not. Whether or not the data DA is updated is confirmed (arrow F5). When the document data DA held in the document editing server 2 is updated to the document data DB, the image forming apparatus 3 acquires the updated document data DB from the document editing server 2 (arrow F6). Then, the image forming apparatus 3 generates a print job based on the document data DB, and replaces the print job JD whose execution start timing is approaching with a print job generated based on the document data DB.

  As described above, when the image forming apparatus 3 according to the present embodiment acquires and prints out the document data DA held in the document editing server 2, the print job generated based on the document data DA is executed. When the start timing approaches, data communication with the document editing server 2 is performed to check whether the document data DA has been updated. If the document data DA has been updated to the document data DB, The updated document data DB is acquired again to generate a print job, and the print job generated based on the document data DA is replaced with the print job generated based on the document data DB. Therefore, the image forming apparatus 3 can print the document data held in the document editing server 2 in the latest state.

  In particular, in the present embodiment, document data DA held in the document editing server 2 may be edited simultaneously by a plurality of users A, B, and C. In such a case, even if one user A gives a print instruction to print out based on the latest version of the document data DA, the image forming apparatus 3 starts executing the corresponding print job. It takes time until the editing operation is performed by other users B and C, and the document data DA may be updated. Even in such a case, the image forming apparatus 3 of the present embodiment automatically re-acquires the latest version of the document data DB when the execution timing of the print job approaches, and based on the latest version of the document data DB. Therefore, the print output based on the latest version of the document data DB desired by the user A can be satisfactorily performed.

  Further, when the image forming apparatus 3 of the present embodiment confirms that the document data DA has been updated in the document editing server 2, the updated document data is sent to the user who has instructed printing of the document data DA. An inquiry may be made as to whether or not to perform print output based on the DB, and the updated document data DB may be acquired based on a response result to the inquiry. With such a configuration, the intention of the user who issued the print instruction can be confirmed, and if the user intends to print out the latest version of the document data DB, the latest version of the document data DB Can be obtained and printed out. Therefore, according to such a configuration, it is possible to confirm the intention of the user who issued the print instruction and perform print output based on the latest version of the document data DB based on the intention of the user.

  Further, when the image forming apparatus 3 according to the present embodiment acquires the document data DA to be printed from the document editing server 2 based on the access information D5, the data acquisition time required until the acquisition of the document data DA is completed. Measure. Then, the image forming apparatus 3 at the timing of the document editing server 2 at least at the timing before the time required for data acquisition before the timing at which the print job generated based on the document data DA acquired from the document editing server 2 is executed. It is configured to check whether or not the document data DA has been updated. According to such a configuration, when the document data DA held in the document editing server 2 has been updated, the image forming apparatus 3 causes the latest version of the document data DB before the execution of the print job is started. When the print job execution start timing comes, the print job can be executed by replacing the print job generated based on the document data DB. Therefore, it is possible to efficiently acquire the latest version of the document data DB and start execution of the print job without delay.

  While the embodiments of the present invention have been described above, the present invention is not limited to the above-described contents, and it goes without saying that various modifications can be applied.

  For example, in the image forming system 1 described above, the case where the document editing server 2 is installed at a location different from the base 6 is illustrated, but the present invention is not limited to this. It doesn't matter.
