Abstract: An object of the present invention is to provide an apparatus and method for ink jet printing which can reduce density unevenness caused by an end deviation condition associated with ink droplets ejected from a print head, regardless of gray scale of a printed image. The present invention thus sets the print duty for a nozzle located at an end of a nozzle array formed in a print head on the basis of the end deviation amount of a position impacted by an ink droplet ejected from the end of the nozzle array.

Abstract: This invention relates to a printer and printing method capable of printing at high quality at a printing boundary where different printing elements can print in the same area of a printing medium. According to this method, when printing by moving a printhead in which a plurality of printing elements are arrayed relatively to a printing medium, the following control are 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.
