In this embodiment, the request issue time is stored in the NVRAM 14 of the image forming apparatus 1 and the allowable time is transferred to the server apparatus 2. When the data is returned from the server device 2, the image forming apparatus 1 adds the request issue time to the allowable time returned together with the data, and compares the added time with the current time to execute the job. Determine whether.

The processing procedure of this embodiment will be described with reference to the flowchart shown in FIG.
When image data stored in the server device 2 is selected from the operation unit 25 of the image forming apparatus 1 and a print instruction is input, the control unit 10 identifies the instructed image data and preset permission values. The time is included in the image acquisition request and output to the server device 2 (step S11). Further, the time when the acquisition request is issued (hereinafter referred to as the request issue time) is stored in the NVRAM 14 (step S12). Upon receiving the image data acquisition request, the server apparatus 2 returns the requested image data and the allowable time received from the image forming apparatus 1 to the image forming apparatus 1.

  When receiving a data response from the server device 2 (step S13), the control unit 10 extracts the allowable time from the received data, extracts the issue time stored in the NVRAM 14, and adds these (step S14). Then, the obtained addition time is compared with the current time. If the addition time exceeds the current time (step S15 / YES), the job is canceled without being executed (step S17). If the addition time does not exceed the current time (step S15 / NO), the job is executed (step S16).

  The allowable time can be arbitrarily set by the user from the operation unit 25.

  An outline of the operation of this embodiment is shown in FIG. In the present embodiment, when the image data acquisition request is output to the server apparatus 2 and waiting for the transfer of the image data, the request issue time stored in the NVARAM 14 is cleared by the operation of the operation unit 25. Then, even if image data is received, control is performed so that the image data is not output.

The processing procedure of this embodiment will be described with reference to the flowchart shown in FIG.
The identification information of the image data and the preset allowable time are included in the image acquisition request from the image forming apparatus 1 and output to the server apparatus 2 (step S21). Further, the time when the acquisition request is issued (hereinafter referred to as request issue time) is stored in the NVRAM 14 (step S22).

  The control unit 10 clears the request issue time or sets NULL when cancel is input by the operation of the operation unit 25 while waiting for the return of data from the server device 2 (step S23). (Step S24). Then, it waits for data to be transferred from the server device 2 (step S25). When data is received from the server device 2 (step S26 / YES or S25 / YES), the control unit 10 determines whether or not the request issue time stored in the NVRAM 14 has been cleared (step S27). If the request issue time is cleared or NULL is set (step S27 / YES), the control unit 10 deletes the image data received from the server device 2 without printing (step S31). ). Other processes are the same as those in the second embodiment described above, and will not be described.

  An outline of the operation of this embodiment is shown in FIG. In this embodiment, for example, when a plurality of documents are acquired from the server device 2 and printing is performed, the request issue time is updated to the time when the reception is completed each time reception of one document is completed. Therefore, the allowable time can be set for each document. For this reason, it is not necessary to change the allowable time in order to download a large amount of data at once.

  The processing procedure of this embodiment will be described with reference to the flowchart shown in FIG. The image forming apparatus 1 of the present embodiment also transmits the identification information of the image data and the allowable time to the server device 2 and stores the request issue time in the NVRAM 14 as in the above-described embodiment. When data is received from the server device 2 (step S33 / YES), the request issue time is added to the allowable time transferred from the server device 2, and the added time is compared with the current time (step S35). If the addition time does not exceed the current time (step S35 / NO), the update issue time is updated to the current time (step S36), and the job is executed (step S37). Each time reception of one document is completed, the request issue time is updated to the data reception completion time. Therefore, the allowable time can be set for each document. When the execution of the job is completed, it is determined whether or not the job for all requests issued to the server device 2 has been processed (step S40). If all the jobs have not been processed (step S40 / NO), the data transmitted from the server device 2 is received, and the above-described steps S33 to S37 are repeated. If all jobs have been processed (step S40 / YES), this flow ends.

  In this embodiment, when a change in the permission time is input from the operation unit 25 after the image data acquisition request is issued, whether or not the input is accepted and the job is executed using the changed allowable time. Determine.

The processing procedure of this embodiment will be described with reference to the flowchart shown in FIG. The control unit 10 includes the identification information of the instructed image data and the request issuance time in the acquisition request and outputs them to the server device 2 (step S41).
Thereafter, the control unit 10 monitors an operation input from the operation unit 25. When the permission time is changed by the operation of the operation unit 25 (step S42), the permission time stored in the NVRAM 14 is rewritten, and the data transmitted from the server device 2 is waited (step S45). When data is received from the server device 2 (step S43 / YES or S45 / YES), the control unit 10 extracts the issue request time from the received data and adds the rewritten allowable time. The addition time is compared with the current time to determine whether or not to execute the job.

  The outline of the operation of this embodiment is shown in FIG. In this embodiment, when an image data acquisition request is output to the server apparatus 2, a job identifier for identifying a job is issued and transmitted to the image forming apparatus 2 together with the image data acquisition request. In the image forming apparatus 2, the issue time when the acquisition request is issued is stored in association with the job identifier. FIG. 13 shows an example of a table stored in the NVRAM 14. When the image data and the job identifier are returned from the server device 2, the allowable time is added to the issue time associated with the job identifier, and the added time is compared with the current time. If the addition time exceeds the current time, cancel without executing the job. If the addition time does not exceed the current time, the job is executed.

The processing procedure of the present embodiment will be described with reference to the flowchart shown in FIG.
When image data stored in the server device 2 is selected from the operation unit 25 of the image forming apparatus 1 and a print instruction is input, the control unit 10 issues a job identifier for identifying the job, and the designated image The data identification information and the job identifier are transmitted to the server device 2 (step S51). The issue time when the acquisition request is issued in association with the job identifier is stored in the NVRAM 14 (step S52).
When the server apparatus 2 receives the image data acquisition request, the server apparatus 2 returns the image data requested for acquisition and the job identifier received from the image forming apparatus 1 to the image forming apparatus 1.

When receiving a data reply from the server device 2 (step S53), the control unit 10 retrieves the job identifier from the data received from the server device 2 and searches the NVRAM 14. Then, the issue time registered in association with the job identifier is detected (step S54). When the issue time is detected, a preset allowable time is added to this (step S55), and the added time is compared with the current time (step S56). If the addition time exceeds the current time (step S56 / YES), the job is canceled without being executed. If the addition time does not exceed the current time (step S56 / NO), the job is executed.
In this embodiment, the allowable time can be arbitrarily set by the user from the operation panel.

  In this embodiment, an allowable time can be set for each job. Therefore, as shown in FIG. 15, the request issue time and the allowable time are stored in the NVRAM 14 in association with the job identifier.

  The processing procedure of this embodiment will be described with reference to the flowchart shown in FIG. When the control unit 10 transmits the identification information of the image data and the job identifier to the server device 2 (step S61), the NVRAM 14 associates the issuance time of this request and the allowable time input from the operation panel with the job identifier. (Step S62). Thereafter, when receiving the data, the control unit 10 extracts a job identifier from the data, and extracts the request issue time and the allowable time stored in the NVRAM 14 (step S64). It is determined whether or not to execute the job by comparing the addition time obtained by adding these times with the current time (step S66).

Note that the above-described control of the third embodiment, the control of the fourth embodiment, and the control of the fifth embodiment can be performed for each job identifier.
FIG. 17 shows an example of a table configured in the NVRAM 14. For each job identifier, a request issuance time and a permission time are registered and managed. When a cancel is input by the operation unit 25, the permission time is cleared or set to NULL as shown in FIG. As a result, the control unit 10 recognizes that the job has been canceled and stops the execution of the job.
FIG. 18 shows a change history of the NVRAM 14 when the request issue time is updated every time reception of one document is completed. Each time one document is received, the request issue time of the corresponding job identifier is changed to the data reception time.
FIG. 19 shows a change history of the NVRAM 14 when an instruction to change the allowable time is input from the operation unit 25 during data standby. When the permission time is changed as shown in FIG. 19, the allowable time of the corresponding job identifier is changed. When the control unit 10 receives data from the server device 2, the control unit 10 determines whether to execute the job by using the permission time written in the NVRAM 14.
