A printer and printing method can print at high quality at a printing boundary where different printing elements can print in the same area of a printing medium. When printing by moving a printhead, in which a plurality of printing elements are arrayed, relatively to a printing medium, the following control is performed. That is, it is checked whether different printing elements are printable in the same area on the printing medium on the basis of input image data. It is checked whether the input image data is used to print a text image or a graphic/halftone image. It is controlled in accordance with the check results to print in the same printable area by the different printing elements by changing respective ratios at which printing elements are used.
