Claim:
A printing apparatus comprising: an input unit configured to input image data; a printing unit configured to perform print processing on a sheet based on the image data input by the input unit; a determination unit configured to determine whether the image data input by the input unit is image data indicating a blank page; a control unit configured to, in a case where the determination unit determines that the image data is not image data indicating a blank page, control the printing unit to perform print processing based on the image data, and in a case where the determination unit determines that the image data is image data indicating a blank page, control the printing unit not to perform print processing based on the image data; and a sheet discharge unit configured to discharge a sheet on which the print processing is performed by the printing unit, wherein, in a case where the input unit inputs image data in order of first image data, second image data, and third image data, and the first image data and the third image data are not image data indicating a blank page, and the second image data is image data indicating a blank page, the sheet discharge unit discharges a sheet on which the print processing is performed based on the first image data on a first sheet stacking unit and discharges a sheet on which the print processing is performed based on the third image data on a second sheet stacking unit which is different from the first sheet stacking unit.
