Abstract: An image forming apparatus includes a print processing portion, a selection processing portion, and an output processing portion. The print processing portion executes a print process based on print data. The selection processing portion, when the print process has been interrupted, selects, as an output destination of the print data processed in the interrupted print process, either an image forming apparatus with which its associated image forming apparatus can communicate, or an external storage apparatus to which its associated image forming apparatus is connected, in accordance with a user operation. The output processing portion executes an external output process for outputting at least one of the print data and unprocessed data to the output destination selected by the selection processing portion after the print process has been interrupted, the unprocessed data being part of the print data on which the print process has not been executed.
