Abstract
A liquid ink printing apparatus printing images includes a printhead having a plurality of nozzles wherein a single power pulse causes two or more nozzles to eject ink simultaneously. The printhead includes an ink directing element having a plurality of ink conduits coupled to an array of spaced nozzles and a transducer element aligned with and mated to the ink directing element. The transducers are spaced a distance apart and each transducer is substantially aligned with at least two or more of the nozzles. The printhead is stepped in a direction transverse to the array of spaced nozzles a stepping distance approximately equal to or less than the distance between transducers. The ink directing element includes a silicon wafer having etched ink conduits or channels holding ink for ejection through the nozzles connected thereto. Each transducer is cooperatively associated with one channel having a fork member coupled to two or more nozzles or is cooperatively associated with two or more channels wherein each channel is connected to one or more nozzles.
