Abstract
A liquid ink, drop on demand page-width printhead comprises a semiconductor substrate, a plurality of drop-emitter nozzles fabricated on the substrate; an ink supply manifold coupled to the nozzles; pressure means for subjecting ink in the manifold to a pressure above ambient pressure causing a meniscus to form in each nozzle; a means for applying heat to the perimeter of the meniscus in predetermined selectively addressed nozzles; a means for controlling the volume of poised drops in the selectively addressed nozzles; and a means for transferrring the poised drops onto the recording media.
