First Claim
1. An image output apparatus connected to another device by a serial bus, comprising:
- communication means for performing communication with the another device through the serial bus and receiving image data transferred by the another device;
image formation control means for controlling to form an image on a print medium based on the image data received by said communication means;
staple control means for controlling to staple a plurality of print media on which image forming is performed; and
detection means for detecting an initialized state of the serial bus during image data reception by said communication means, wherein in a case where said detection means detects the initialized state of the serial bus, said communication means requests the another device to transfer the image data and receives the image data again, then said image formation control means controls to form an image on a print medium based on the received image data, and said staple control means controls to staple print media on which image forming is performed.

Abstract
In an image output apparatus which performs printing based on transferred data, when bus reset occurs during isochronous data transfer through a serial bus, the data transfer is suspended and a print error is caused. Therefore, when bus reset occurs during image data transfer through the serial bus, transferring and outputting of image data is performed again, and stapling is performed for proper stapling. Similarly, when bus reset occurs, transferring and outputting of image data is suspended, the printouts whose printing has been suspended are discharged to a dedicated bin provided for erroneous printouts, and transferring and outputting of the image data is performed again. Accordingly, an erroneous printout caused by bus reset is not intermingled with proper printouts on the same bin.
