Abstract

A printing apparatus includes an input unit configured to input a print job, a print unit configured to perform print processing onto a print medium based on the print job input by the input unit, a receiving unit configured to receive a request for shutting off power supply of the printing apparatus, an execution unit configured to execute processing for shifting to a state where power supply of the print unit can be shut off, in response to the fact that the request has been received by the receiving unit, and a control unit configured to perform control, if a request for shutting off a power supply of the printing apparatus is received by the receiving unit, to prevent the print processing based on the print job from being executed, and on the other hand, to permit execution of processing based on another job different from the print job.

Claims

1. A printing apparatus comprising:

an input unit configured to input a print job;

a print unit configured to perform print processing onto a print medium based on the print job input by the input unit;

a receiving unit configured to receive a request for shutting off power supply of the printing apparatus;

an execution unit configured to execute processing for shifting to a state where power supply of the print unit can be shut off, in response to the fact that the request has been received by the receiving unit; and

a control unit configured to perform control, if a request for shutting off a power supply of the printing apparatus is received by the receiving unit, to prevent the print processing based on the print job from being executed, and on the other hand, to permit execution of processing based on another job different from the print job.

2. The printing apparatus according to claim 1, wherein the print unit includes a fixing unit configured to thermally fix a developer on the print medium, and

wherein a state where the print unit can be powered off is a state where a temperature of the fixing unit falls below a predetermined temperature.

3. The printing apparatus according to claim 1, wherein the control unit, after executing processing of shifting to a state where the execution unit can power off the print unit, performs control to prevent input of print job from being performed by the input unit.

4. The printing apparatus according to claim 1, wherein the control unit, after all jobs under execution are completed, performs control to shut off power supply of the printing apparatus.

5. The printing apparatus according to claim 1, further comprising:

a storage unit configured to store data,

wherein the control unit, if a request for shutting off power supply of the printing apparatus is received by the receiving unit, performs control to register the print job on the storage unit as a standby job, and to change to a job performed without using the print unit, and to permit execution of the changed job.

6. The printing apparatus according to claim 5, wherein, if the print job is a job which includes data described using a page description language, the control unit stores image data obtained by rasterizing the data described using the page description language in the storage unit as standby job.

7. The printing apparatus according to claim 5, wherein the control unit, if the standby jobs are stored in the storage unit when the printing apparatus is activated, permits execution of the standby job.

8. The printing apparatus according to claim 7, wherein the control unit, if the standby jobs are stored in the storage unit when the printing apparatus is activated, displays a list of the standby jobs on a display unit.

9. The printing apparatus according to claim 1, wherein the receiving unit receives a request for shutting off the power supply of the printing apparatus from an operator of the printing apparatus.

10. A control method for a printing apparatus comprising:

inputting a print job;

performing print processing onto a print medium based on the print job input by the input unit;

receiving a request for shutting off the power supply of the printing apparatus;

executing processing for shifting to a state where power supply of the print unit can be shut off, in response to the fact that the request has been received by the receiving unit; and

performing control, if a request for shutting off a power supply of the printing apparatus is received by the receiving unit, to prevent the print processing based on the print job from being executed, and on the other hand, to permit execution of processing based on another job different from the print job.

11. A computer-readable storage medium storing a control program for causing a computer to perform a method of controlling a printing apparatus connected to an external device, the printing apparatus comprising:

an input unit configured to input a print job;

a print unit configured to perform print processing onto a print medium based on the print job input by the input unit;

a receiving unit configured to receive a request for shutting off power supply of the printing apparatus;

an execution unit configured to execute processing for shifting to a state where power supply of the print unit can be shut off, in response to the fact that the request has been received by the receiving unit; and

a control unit configured to perform control, if a request for shutting off a power supply of the printing apparatus is received by the receiving unit, to prevent the print processing based on the print job from being executed, and on the other hand, to permit execution of processing based on another job different from the print job.
