ABSTRACT:
A printhead for an Inkjet Printer is disclosed. The printhead has a large number of nozzle assemblies. Each nozzle assembly has an inkjet nozzle having an actuator for ejecting an ink droplet from the inkjet nozzle when a resistive element of the actuator is heated by an electrical current, a drive transistor for providing an energy pulse to the resistive element of said actuator, and control logic for controlling said drive transistor. Nozzles are spaced from other nozzles ejecting ink of a same color by less than 25 μm in a direction transverse to the direction of movement of a print media upon which ink is ejected.
