Patent ID: 7546056

Claim:
A printing apparatus configured to execute a duplex print job which includes printing on both surfaces of a sheet, comprising: an input unit adapted to input the duplex print job; a printing unit adapted to print on both surfaces of the sheet on the basis of the duplex print job input by the input unit; an inversion transport unit adapted to turn over the sheet printed by the printing unit and re-transport the sheet to the printing unit; a feeder unit adapted to feed the sheet to the printing unit; a sheet output unit adapted to stack the sheet subjected to the print process by the printing unit; and a control unit adapted to control the printing apparatus to perform printing in either one of an automatic duplex print mode and a manual duplex print mode, the automatic duplex print mode being a mode in which printing is performed on a first surface of a sheet, the sheet is turned over by the inversion transport unit, and printing is performed on a second surface of the sheet, the manual duplex print mode being a mode in which printing is performed on a first surface of a sheet, the sheet is output to the sheet output unit, the output sheet is fed from the feeder unit, and printing is performed on a second surface of the sheet; wherein, when all of the pages of the duplex print job are to be printed on sheets of a first attribute, the control unit executes printing in the automatic duplex print mode, and wherein, when the duplex print job contains pages to be printed on sheets of the first attribute and pages to be printed on sheets of a second attribute different from the first attribute, the control unit executes printing in the manual duplex print mode.
