Abstract

A printer is provided having, supported by a support structure, a print assembly and feed mechanism for feeding print media though a printing zone. The print assembly has an elongate carrier mounted to the support structure which mounts printhead integrated circuits and control circuitry connected to the printhead ICs. The elongate printing zone defined by the printhead ICs is at least 914 mm. Each printhead IC incorporates nozzle arrangements having a nozzle, ink chamber, ink inlet, actuator, and drive circuit to achieve ink ejection at more than one billion ink drops per second. The printhead ICs are each positioned at a common angle of greater than zero degrees and less than ninety degrees with respect to a straight line extending at right angles to a feed direction of print media, with consecutive ends of the printhead integrated circuits overlapping to ensure continuous printing in the printing zone.
