Patent ID: 8294929

Claim:
An image forming apparatus that selects a first paper-delivery destination and performs a print output at the first paper-delivery destination, the image forming apparatus comprising: a print-process managing unit that controls the print output and that divides a print job into a plurality of print processes, each print setting of the print job corresponding to one of the plurality of print processes, the plurality of print processes being executed for each duplicate instance of the print job; and a sample-print-output controlling unit that controls execution of a sample print output by generating, in response to a sample-print-output request that is received while the print job is executing, an interrupt of a scheduled print process and outputting the sample print output that is a duplicate of a scheduled print process to a second paper-delivery destination changed by the print-process managing unit; wherein the scheduled print rocess is either one of a print process scheduled to be started after a time point at which the sample-print-output request is received and a print process that is being executed at a time point at which the sample-print-output request is received.
