If an inter sheet on a designated feed tray during execution of a print job is lacking, and when a setting received via an operation unit is for a first mode, a control unit switches a feed source from the designated feed tray to another feed tray on which an inter sheet of the same size has been placed and continues the print job, and when the setting is for a second mode, interrupts the print job without switching the feed source from the designated feed tray to another feed tray. In a case where a plurality of feed trays are designated as a feed source, the control unit interrupts the print job without switching the feed source from the feed tray in which the inter sheet is lacking to another feed tray even if the setting is for the first mode.
