Abstract

If a user specifies shutdown of the power supply of an apparatus from a console, another apparatus connected to the same network is notified so as not to issue a request for a new shared job, and it is determined whether a scheduled shared job exists. The display on a display screen is changed in accordance with the result of the determination. If it is determined that a shared job exists, shutdown of the power supply is controlled in accordance with the status of execution of the shared job.

Claims

1. An image processing apparatus, comprising:

a scanner that scans an original to generate image data;

a printer that performs printing based on the image data generated by the scanner or image data transmitted from an external apparatus connected to the image processing apparatus via a network;

an operation unit that performs designation or input by a user;

a determination unit that determines whether or not the image data transmitted from the external apparatus is printing in the printer when a shutdown of a power supply is designated from the operation unit by the user; and

a control unit that, in a case where it is determined by the determination unit that the image data transmitted from the external apparatus is printing, performs the shutdown of the power supply after completing the print, and in a case where it is determined by the determination unit that the image data transmitted from the external apparatus is not printing, performs the shutdown of the power supply without waiting for the print completion even if the image data generated by the scanner is printing in the printer.

2. The apparatus according to claim 1, further comprising a notification unit that notifies the external apparatus not to transmit new image data when the shutdown of the power supply is designated from the operation unit by the user.

3. The apparatus according to claim 1, wherein the operation unit has a display screen displays information, and

wherein, on the display screen, performing the shutdown of the power supply immediately is displayed in a case where it is determined by the determination unit that the image data transmitted from the external apparatus is not printing, and performing the shutdown of the power supply later is displayed in a case where it is determined by the determination unit that the image data transmitted from the external apparatus is printing.

4. The apparatus according to claim 1, wherein the image data transmitted from the external apparatus is image data generated by a scanner prepared for the external apparatus.

5. An image processing apparatus, comprising:

a scanner that scans an original to generate image data;

a printer that performs printing based on the image data generated by the scanner or image data transmitted from an external apparatus connected to the image processing apparatus via a network;

an operation unit that performs designation or input by a user;

a determination unit that determines whether or not the image data transmitted from the external apparatus is a print waiting state when a shutdown of a power supply is designated from the operation unit by the user; and

a control unit that, in a case where it is determined by the determination unit that the image data transmitted from the external apparatus is the print waiting state, performs the shutdown of the power supply after print completion of the image data of the print waiting state, and in a case where it is determined by the determination unit that the image data transmitted from the external apparatus is not the print waiting state, performs the shutdown of the power supply without waiting for the print completion even if the image data generated by the scanner is printing or the print waiting state in the printer.

6. The apparatus according to claim 5, further comprising a notification unit that notifies the external apparatus not to transmit new image data when the shutdown of the power supply is designated from the operation unit by the user.

7. The apparatus according to claim 5, wherein the operation unit has a display screen displays information, and

wherein, on the display screen, performing the shutdown of the power supply immediately is displayed in a case where it is determined by the determination unit that the image data transmitted from the external apparatus is not the print waiting state, and performing the shutdown of the power supply later is displayed in a case where it is determined by the determination unit that the image data transmitted from the external apparatus is the print waiting state.

8. The apparatus according to claim 5, wherein the image data transmitted from the external apparatus is image data generated by a scanner prepared for the external apparatus.

9. A control method for an image processing apparatus having a scanner that scans an original to generate image data, a printer that performs printing based on the image data generated by the scanner or image data transmitted from an external apparatus connected to the image processing apparatus via a network, and an operation unit that performs designation or input by a user, the method comprising:

determining whether or not the image data transmitted from the external apparatus is printing in the printer when a shutdown of a power supply is designated from the operation unit by the user; and

in a case where it is determined in the determining step that the image data transmitted from the external apparatus is printing, performing the shutdown of the power supply after completing the print, and in a case where it is determined in the determining step that the image data transmitted from the external apparatus is not printing, performing the shutdown of the power supply without waiting for the print completion even if the image data generated by the scanner is printing in the printer.

11. A non-transitory computer-readable recording medium on which a program has been recorded for causing a computer to execute the control method set forth in claim 9.

10. A control method for an image processing apparatus having a scanner that scans an original to generate image data, a printer that performs printing based on the image data generated by the scanner or image data transmitted from an external apparatus connected to the image processing apparatus via a network, and an operation unit that performs designation or input by a user, the method comprising:

determining whether or not the image data transmitted from the external apparatus is a print waiting state when a shutdown of a power supply is designated from the operation unit by the user; and

in a case where it is determined in the determining step that the image data transmitted from the external apparatus is the print waiting state, performing the shutdown of the power supply after print completion of the image data of the print waiting state, and in a case where it is determined in the determining step that the image data transmitted from the external apparatus is not the print waiting state, performing the shutdown of the power supply without waiting for the print completion even if the image data generated by the scanner is printing or the print waiting state in the printer.

12. A non-transitory computer-readable recording medium on which a program has been recorded for causing a computer to execute the control method set forth in claim 10.
