Abstract:
A printhead device for use in printing a pixel dot matrix on a print medium, comprising:an array of drop generators, at least one of said drop generators having a plurality of nozzles; at least one heating element located within said at least one drop generator; said plurality of nozzles configured in a predetermined layout such that as said at least one drop generator traverses a print medium target pixel as said print head is scanned across the print medium, said plurality of nozzles ejects ink droplets to deposit a distribution of ink dots on the print medium upon an activation of said at least one heating element; and at least one nozzle of said plurality of nozzles formed to direct an ink droplet of said ink droplets to deposit an ink dot of said distribution of ink dots on the print medium substantially outside said print medium target pixel upon said activation of said at least one heating element.
