ABSTRACT:
In a print apparatus and method in which the print head having printing elements to form print dots is made to scan over a printing medium in a predetermined direction to form a printed image, the drive timing intervals between a plurality of dots formed in the scan direction by the same printing element are changed in a cycle smaller than a cycle in which a printed image variation appears, in order to eliminate the printed image unevenness that cyclically appears due to variations in the manufacturing errors of a rotary drive source and other mechanisms for performing the scanning. By driving the printing elements in this way, it is possible to change the distance between adjoining dots in the predetermined direction in a short cycle and thereby render the cyclic unevenness caused by the rotary drive source visually impossible to recognize.
