  • a substrate;

    an inkjet nozzle disposed on said substrate, said inkjet nozzle having an actuator for ejecting an ink droplet from said inkjet nozzle when a resistive element of said actuator is heated by an electrical current;

    a drive transistor for providing an energy pulse to said resistive element of said actuator; and

    control logic for controlling said drive transistor,wherein nozzles are spaced from other nozzles ejecting ink of a same color by less than 25 μ

    m in a direction transverse to the direction of movement of a print media upon which ink is ejected, andwherein the resistive element of said actuator is spaced apart from said substrate.
