  In the following description, a printer control system in which a printer executes a print job received from a personal computer (PC) is given as an example of a device control system. A device (peripheral device) applied to the device control system is not limited to a printer, and may be another device such as a scanner. In particular, a network device that can receive jobs from a plurality of terminal devices via a network is suitable. Further, the terminal device is not particularly limited to a PC as long as it can transmit a job to be executed by a device.

[First Embodiment]
FIG. 1 is a block diagram illustrating a configuration of a printer control system 11 according to the first embodiment. In the printer control system 11, a PC 21 is connected to a printer 31 via a network. In this figure, only one PC 21 is shown, but actually, a plurality of PCs and the like having the same configuration are connected to the printer 31 via a network.

  The PC 21 is configured as a computer mainly including a CPU, and the application 51 and the printer driver 52 operate as software modules by the CPU. The printer driver 52 generates a print job for causing the printer 31 to print the document data based on the document data generated by the application 51, and transmits the print job to the printer 31 from the interface 53.

  The printer driver 52 generates a print job (color print job) for requesting the printer 31 to perform color printing of the document data when the document data is composed of colors (including colors other than black and white). To do.

  The printer 31 includes a device unit 61 that executes a print job received from the PC 21. The device unit 61 is configured to be capable of color printing. The printer 31 includes a computer mainly having a CPU. The CPU controls execution of a print job in the device unit 61, and also includes a time zone determination unit 65, a calendar unit 66, and a job storage unit 67. Operates as a software module. These operations are performed according to a printer control program (device control program).

  FIG. 2 is a flowchart showing the operation of the printer 31 (operation according to the printer control program).

  First, when the time zone determination unit 65 receives a color print job from the PC 21 via the interface 63 (S11), a calendar unit in which a time zone for prohibiting color printing (or a time zone for allowing color printing) is set. It is determined whether or not the current time is a time zone in which color printing is prohibited in cooperation with 66 (S12).

  If the current time is a time zone in which color printing is permitted (S12: YES), the time zone determination unit 65 outputs a color print job to the device unit 61, and the device unit 61 outputs the color print job. Is executed (S13).

  On the other hand, when the current time is a time zone in which color printing is prohibited (S12: NO), the time zone determination unit 65 outputs a color print job to the job storage unit 67, and the job storage unit 67 performs color printing. The print job is stored in the memory 68 (S14). Here, the time zone determination unit 65 may notify the PC 21 that the color print job has been accumulated.

  In addition, the job storage unit 67 permits the time zone determination unit 65 to perform color printing until the storage limit time is exceeded (S15: NO) while the color print job is stored in the memory 68. It is determined periodically whether or not the time zone is reached (S12).

  If the current time is a time zone in which color printing is permitted (S12: YES), the time zone determination unit 65 selects a color print job stored in the memory 68 by the job storage unit 67. The data is output to the device unit 61, and the device unit 61 executes a color print job (S13).

  On the other hand, if the current time remains the time zone in which color printing is prohibited (S12: NO), the job storage unit 67 keeps the color print job stored in the memory 68. (S14).

  If the storage limit time is exceeded while the color print job is stored in the memory 68 (S15: YES), the job storage unit 67 deletes the stored color print job from the memory 68 (S16). Here, the timing at which the color print job is deleted is assumed to be when a predetermined accumulation limit time is exceeded, but is not limited to this. For example, when the color print job accumulated in the memory 68 exceeds a predetermined capacity, etc. It can also be. The job storage unit 67 may notify the PC 21 that the color print job has been deleted.

  As described above, the time zone determination unit 65 does not supply a color print job to the device unit 61 when the current time is a time zone in which color printing is prohibited, so that the time zone determination unit 65 can perform the It limits costly color printing. As a result, for example, by setting a time zone in which the user is concentrated during the day as a time zone in which color printing is prohibited, it is possible to reduce congestion and reduce costs.

  In addition, by storing the color print job by the job storage unit 67, the color print job can be made to stand by until a time zone in which color printing is permitted. Thereby, for example, color printing can be performed in a time zone with less congestion, and therefore, congestion can be expected to be reduced.

  Further, by deleting the color print job stored in the job storage unit 67 at a predetermined timing, the color print job that has become unnecessary by the user performing alternative printing or the like is stored for a long time. There is nothing.

  Next, the calendar unit 66 will be described. The calendar unit 66 is preset with a time zone in which color printing is prohibited (or a time zone in which color printing is allowed). The time zone for prohibiting color printing may be set by a user operation on an operation panel (not shown) of the printer 31 or by a user operation on a terminal device connected via a network. Anyway.

  Also, the setting of the time zone for prohibiting color printing can be performed by setting the start date and time and the end date and time of the time zone for prohibiting color printing, for example. It is also possible to set the start time and end time of the time zone in which color printing is prohibited and set the date on which this is repeated. The setting of the repeated date includes, for example, variations such as every day, weekdays (Monday to Friday), weekends (Saturday and Sunday), predetermined day of the week, and predetermined date. It is also possible to set a time period for prohibiting color printing on a daily basis.

  In the printer control system 11 described above, the configuration of the time zone determination unit 65, the calendar unit 66, the job storage unit 67, and the memory 68 is included in the printer 31. However, the configuration is not limited to this, and is shown in FIG. Like the printer control system 12, a printer control device (device control device) 41 having these configurations may be provided separately from the printer 32. In the printer control system 12, the printer control device 41 transmits the color print job received from the PC 21 to the printer 32 when the current time is a time zone in which color printing is permitted.

[Second Embodiment]
FIG. 4 is a block diagram showing the configuration of the printer control system 13 according to the second embodiment. In the printer control system 13, the PC 22 includes a time zone determination unit 55 and a calendar unit 56. These are the same configurations as the time zone determination unit 65 and the calendar unit 66 of the printer 33. Further, the contents of the calendar section 56 of the PC 22 are synchronized with the contents of the calendar section 66 of the printer 33.

  Here, the operations of the printer driver (driver main body) 52, the time zone determination unit 55, and the calendar unit 56 included in the PC 22 are performed according to a printer driver program (device driver program).

  FIG. 5 is a flowchart showing the operation of the PC 22 (operation according to the printer driver program) and the operation of the printer 33 (operation according to the printer control program).

  First, in the PC 22, when the printer driver 52 generates a color print job based on the document data generated by the application 51 (S <b> 21), the time zone determination unit 55 cooperates with the calendar unit 56 so that the current time is color. It is determined whether or not it is a time zone during which printing is prohibited (S22).

  If the current time is a time zone in which color printing is permitted (S22: YES), the printer driver 52 transmits a color print job to the printer 33 (S23).

  On the other hand, if the current time is a time zone in which color printing is prohibited (S22: NO), the printer driver 52 displays the selection screen on a display unit (not shown), and performs color printing. The user is prompted to select whether to forcibly execute the job (S24). When the user operates the operation unit (not shown) and selects to forcibly execute the color print job (S24: YES), the printer driver 52 forcibly executes the color print job. After the command is added (S25), it is transmitted to the printer 33 (S23). On the other hand, when the user operates the operation unit (not shown) to make a selection not to forcibly execute the color print job (S24: NO), the color print job is terminated.

  Next, in the printer 33, when the time zone determination unit 65 receives a color print job from the PC 21 via the interface 63 (S11), the current time prohibits color printing in cooperation with the calendar unit 66. It is determined whether or not it is a time zone, and it is determined whether or not a forced execution command is added to the received color print job (S17).

  When the current time is a time zone in which color printing is permitted, or when a forced execution command is added to the received color print job (S17: YES), the time zone determination unit 65 The color print job is output to the device unit 61, and the device unit 61 executes the color print job (S13).

  On the other hand, when the current time is a time zone in which color printing is prohibited, and when the forced execution command is not added to the received color print job (S17: NO), the time zone determination unit 65 The color print job is output to the job storage unit 67, and the job storage unit 67 performs processing such as storing the color print job in the memory 68 (S14 to S16).

  As described above, since the PC 22 has the time zone determination unit 55, when the current time is a time zone in which color printing is prohibited, the PC 22 does not transmit a color print job to the printer 33. Can reduce the processing load. This is effective when the use of the printer 33 is concentrated.

  Further, when forcibly executing a color print job, the PC 22 adds a forcible execution command to the color print job and transmits it to the printer 33, and the printer 33 is in a time zone in which color printing is prohibited. Even in some cases, by executing a color print job, it is possible to deal with users who absolutely need color printing.

  In the PC 22, the time zone determination unit 65 determines whether or not the current time is a time zone in which color printing is prohibited, and the printer driver 52 adds a forced execution command to the color print job and transmits it. As a result, when the current time is a time zone in which color printing is permitted, a forced execution command is not added to the color print job, and the amount of data transmitted to the printer 33 can be reduced.

  Further, since the contents of the calendar section 56 of the PC 22 and the contents of the calendar section 66 of the printer 33 are synchronized, it is determined whether or not the current time is a time zone in which color printing is prohibited. Judgment can be made. Further, since the printer 33 includes the calendar unit 66, the contents of the calendar unit 66 can be reflected on a plurality of PCs connected via the network.

[Third Embodiment]
FIG. 6 is a block diagram showing the configuration of the printer control system 14 according to the third embodiment. In the printer control system 14, the printer 34 has a determination unit 69 including a time zone determination unit 65 and an input determination unit 64.

  In this determination unit 69, the time zone determination unit 65 determines whether or not the current time is a time zone in which color printing is prohibited in cooperation with the calendar unit 66, and the input determination unit 64 determines that the printer 34 It is determined whether or not a signal permitting execution of the color print job is input by a user operation (for example, pressing a button) on the operation panel (not shown). Such an operation of the determination unit 69 is performed according to a printer control program.

  FIG. 7 is a flowchart showing the operation of the printer 34 (operation according to the printer control program).

  First, in the printer 34, when the determination unit 69 receives a color print job from the PC 21 via the interface 63 (S11), the input determination unit 64 of the determination unit 69 permits the execution of the color print job by a user operation. It is determined whether or not a signal has been input (S18).

  When a signal to permit is input (S18: YES), the determination unit 69 outputs a color print job to the device unit 61, and the device unit 61 executes the color print job (S13).

  On the other hand, when the signal to permit is not input (S18: NO), the time zone determination unit 65 of the determination unit 69 is the time zone in which color printing is prohibited by the cooperation with the calendar unit 66. It is determined whether or not a forced execution command is added to the received color print job (S17).

  When the current time is a time zone in which color printing is permitted, or when a forced execution command is added to the received color print job (S17: YES), the determination unit 69 performs color printing. The job is output to the device unit 61, and the device unit 61 executes a color print job (S13).

  On the other hand, when the current time is a time zone in which color printing is prohibited, and when the forced execution command is not added to the received color print job (S17: NO), the determination unit 69 performs color printing. The job is output to the job storage unit 67, and the job storage unit 67 performs processing such as storing a color print job in the memory 68 (S14 to S16).

  In the above description, an example in which a signal for permitting execution of a color print job is input by a user operation (for example, pressing a button) on an operation panel (not shown) of the printer 34 has been described. For example, when a control card is inserted into a card reader (not shown), when a password is input from an operation panel (not shown), or when a password is input from a terminal device via a network A signal permitting the execution of the color print job may be input when the user performs a predetermined operation such as the above.

  As described above, it is possible to more appropriately limit color printing by determining whether or not a signal permitting execution of a color print job based on a predetermined operation has been input.

  Note that the present invention is not limited to the above-described format.

  For example, the printers 31 to 34 may be provided with a job totaling unit that counts the reception frequency of print jobs. By this job totaling unit, the reception frequency of all print jobs for each time zone and the reception frequency for each color print job time zone are totaled, so that the user prohibits color printing based on the total result. The belt can be judged appropriately. Alternatively, a predetermined threshold may be set, and a time zone in which the reception frequency exceeds the threshold may be automatically set as a time zone in which color printing in the calendar unit 66 is prohibited.

  Further, the setting of the time zone in which the job totaling unit counts can be performed in the same manner as the time zone setting for prohibiting color printing in the calendar unit 66 as described above. For example, it can be performed by setting the start date and time and the end date and time of the time zone for aggregation. Moreover, it is also possible to set the start time and end time of the time zone in which aggregation is performed and to set the date on which this is repeated. The setting of the repeated date includes, for example, variations such as every day, weekdays (Monday to Friday), weekends (Saturday and Sunday), predetermined day of the week, and predetermined date. In addition, the time zone for aggregation can be set on a daily basis.
