The execution of an image processing job is limited using a printing amount by an image processing job that has already been executed and a printing amount that is scheduled to be printed by an image processing job that has already been transmitted but not yet executed. To accomplish this, a multi-function peripheral manages a first printing amount that has already been printed by a executed print job and a second printing amount that is scheduled to be printed by a print job that has been transmitted from the multi-function peripheral to a printer and that has not yet been executed in association with a user ID, and determines, before transmitting the print job, whether or not the total of a third printing amount that is scheduled to be printed by the print job, the first printing amount and the second printing amount exceeds an upper limit amount.
