Ink jet printhead for high definition printing and method for operating same

摘要

The printhead according to the present invention is mechanically and electrically interchangeable on an ink jet dot printer with a known head, from which it differs substantially by having a different geometrical disposition of the nozzles, arranged in two parallel vertical rows at a constant pitch of 1/150<th> of an inch, where the corresponding nozzles of the two rows are staggered by 1/600<th> of an inch in order to allow printing with a definition of at least 600 X 600 dots/inch by performing two consecutive print passes spaced apart by a line feed movement of size equal to 1/300<th> of an inch. <IMAGE>
