## Abstract

A printing apparatus is an apparatus capable of performing double-sided printing on a sheet, and is provided with a receiving portion and a control portion. The receiving portion receives an instruction for changing a sheet having one side printed that is set to a paper feed tray into a sheet having both sides printed with same printing content. The control portion performs control, when the instruction is received, to feed the sheet having one side printed from the paper feed tray, and when the fed sheet is an odd-numbered page and is a final page, to discharge the sheet without newly performing printing, and when the fed sheet is an odd-numbered page and is not a final page, to print information printed on a next even-numbered page on a back side of the sheet.
