Document Type and Number:
WIPO Patent Application WO2004059430
Kind Code:
A3
Abstract:
An integrated circuit in an ink jet printhead selectively activates one or more printing elements on the printhead based on a multi-dimensional addressing scheme.The integrated circuit includes a plurality of pass switching (PS), power switching (PG), and one or more ground switching (GS) devices for selectively connecting one or more power switching devices to ground to activate one or more of the printing elements (H) to print an image on a print medium.
