Abstract

If another person comes close to a printing apparatus or print control apparatus during output of a print job by authenticated printing, he/she may accidentally glance at an output material, and private information or confidential information to be hidden may leak. To solve this problem, a print control apparatus according to an embodiment of this invention executes the following control processing. That is, if a received print job is an authenticated print job requiring authentication processing and there is a person nearby the print control apparatus other than the executor of the authenticated print job, a selection screen for accepting execution or holding of printing is displayed. In accordance with an instruction input to the selection screen, printing of the authenticated print job by the printing unit is controlled.

First claim

What is claimed is:

1. A print control apparatus for controlling a print unit configured to print an image on a print medium based on a print job, comprising:
a reception unit configured to receive the print job;
a determination unit configured to, in a case where the print job received by the reception unit is an authenticated print job requiring authentication processing, determine whether there is a plurality of persons near the print control apparatus;
a hold unit configured to, in a case where it is determined by the determination unit that there is a plurality of persons near the print control apparatus, hold print processing based on the authenticated print job; and
a control unit configured to, in a case where a state in which there is a plurality of persons near the print control apparatus has changed to a state in which there is a single person near the print control apparatus, restart the print processing held by the hold unit,
wherein a print product produced by printing the image on the print medium by restarting the held print processing is discharged onto a discharge unit of the print control apparatus, and
the determination unit, the hold unit, and the control unit are implemented by a processor.

2. The apparatus according to claim 1 , further comprising an authentication unit configured to authenticate upon executing the authenticated print job,
wherein the authentication unit is implemented by the processor.

3. The apparatus according to claim 1 , further comprising a display control unit configured to, in a case where the print job received by the reception unit is an authenticated print job requiring authentication processing and there is a plurality of persons near the print unit, display a selection screen which prompts to select either print execution or print hold,
wherein in a case where the print hold is selected in the selection screen, the hold unit holds the print processing based on the authenticated print job, and
the display control unit is implemented by the processor.

4. The apparatus according to claim 3 , wherein
in a case where the print execution is selected in the selection screen, the control unit monitors whether the plurality of persons is near the print control apparatus during execution of authenticated printing, and
in a case where it is detected that the plurality of persons is near the print control apparatus during the execution of the authenticated printing, the display control unit displays the selection screen.

5. The apparatus according to claim 3 , wherein in the case where the print hold is selected, the control unit controls to discharge a white blank sheet in addition to an already printed and discharged print medium.

6. The apparatus according to claim 3 , wherein the display control unit further displays a message indicating a situation near the print control apparatus.

7. The apparatus according to claim 6 , wherein the display control unit further displays a distance between the print control apparatus and a wireless communication device of another person.

8. The apparatus according to claim 1 , further comprising:
a communication unit configured to perform short distance wireless communication;
an estimation unit configured to estimate a distance between the print unit and a wireless communication device by performing short distance wireless communication with the wireless communication device nearby near the print unit by the communication unit; and
a comparison unit configured to compare the distance estimated by the estimation unit with a predetermined distance,
wherein, based on a result of comparison by the comparison unit, the determination unit determines whether there is a plurality of persons near the print control apparatus, and
the estimation unit and the comparison unit are implemented by the processor.

9. The apparatus according to claim 8 , wherein
the communication unit performs short distance wireless communication using Bluetooth® and receives an advertisement packet from the wireless communication device, and
the estimation unit estimates the distance, based on a reception intensity of the received advertisement packet and a transmission power set in the advertisement packet.

10. A print control method in a print control apparatus for controlling a print unit configured to print an image on a print medium based on a print job, comprising:
receiving the print job;
in a case where the received print job is an authenticated print job requiring authentication processing, determining whether there is a plurality of persons near the print control apparatus;
in a case where there is a plurality of persons near the print control apparatus, holding print processing based on the authenticated print job; and
in a case where a state in which there is a plurality of persons near the print control apparatus has changed to a state in which there is a single person near the print control apparatus, restarting the held print processing,
wherein a print product produced by printing the image on the print medium by restarting the held print processing is discharged onto a discharge unit of the print control apparatus.

11. The method according to claim 10 , further comprising authenticating upon executing the authenticated print job.

12. The method according to claim 10 , further comprising:
in a case where the received print job is an authenticated print job requiring authentication processing and there is a plurality of persons near the print unit, displaying a selection screen which prompts to select either print execution or print hold; and
in a case where the print hold is selected in the selection screen, holding the print processing based on the authenticated print job.

13. The method according to claim 12 , wherein
in a case where the print execution is selected in the selection screen, whether the plurality of persons is near the print control apparatus is monitored during execution of authenticated printing, and
in a case where it is detected that the plurality of persons is near the print control apparatus during the execution of the authenticated printing, the selection screen is displayed.

14. The method according to claim 12 , further comprising, in the case where the print hold is selected, discharging a white blank sheet in addition to an already printed and discharged print medium.

15. The method according to claim 12 , wherein in the displaying, a message indicating a situation near the print control apparatus is further displayed.

16. The method according to claim 15 , wherein in the displaying, a distance between the print control apparatus and a wireless communication device of another person is further displayed.

17. The method according to claim 12 , further comprising, in a case where the plurality of persons is detected and the print execution is selected, controlling the print unit to perform high speed printing after the selection.

18. The method according to claim 10 , further comprising:
performing short distance wireless communication;
estimating a distance between the print unit and a wireless communication device by performing short distance wireless communication with the wireless communication device near the print control apparatus; and
comparing the estimated distance with a predetermined distance,
wherein in the determining, based on a result of the comparison, it is determined whether there is a plurality of persons near the print control apparatus.

19. The method according to claim 18 , wherein
