Abstract
A printing apparatus sequentially prints a plurality of images on a first surface of a sheet, and then sequentially prints a plurality of images on a second surface that is a back surface of the first surface. When a state of a printing unit is determined not to be normal when printing on the first surface, the printing apparatus executes processing for maintenance by using a sheet different from the sheet used for printing on the first surface.
