Abstract

A printing apparatus, which can make the maximum current low in its driving circuit and can prevent banding in high efficiency and also achieve a low cost, is provided. When an image is formed on a printing medium by that a print head having a plurality of nozzles moves in two orthogonal directions, that is, a main scanning direction and a sub scanning direction, the print head having a plurality of nozzles is supposedly divided into P pieces of independent printing element groups which have the same printing elements, in this, the P is an integer two or more. And the main scanning and the sub scanning are controlled so that each of the P pieces of independent printing element groups can print the printing pixels on the printing medium. And each of the P pieces of independent printing element groups is selected so that the printing pixels are not printed in overlap, and a shingling process is realized.
