A printing apparatus includes a generation unit for generating one page of a print image which is larger than one sheet of paper, and a printing unit for performing printing on one sheet of paper based on one page of the print image, which is larger than the paper and generated by the generation unit. The generation unit, based on an allocation number representing the number of pages to be allocated to one sheet of paper, performs clipping to remove a portion of the print data which can be printed by the printing unit to prevent the print image of each page which is not printed from deviating the image of each page, when a plurality of pages of print data printed on one sheet of paper are generated.
