Abstract
A printing apparatus having a plurality of print element arrays including a plurality of printing elements that are time-share driven achieves both improvement of quality at an image edge, and maintenance of uniformity with respect to inclination error between print element arrays. In a case where the plurality of printing elements of the print element array that discharges ink having the highest density are driven, and dots of image data in the array direction of the printing elements are printed so that the dots are arranged along a specified line in the array direction of the printing elements. Whereas the plurality of printing elements of a different print element array are driven, and dots of the image data in the array direction of those printing elements are printed so that each dot is displaced by a displacement amount for the each dot with respect to the specified line.
