Abstract
An inkjet printhead includes a compact substrate having transmission circuitry such as actuation signal lines and address circuitry and ground lines in connection with resistors in a plurality of vaporization chambers on the substrate, with a minimal number of interconnect junctions located at both ends of the substrate. A print cartridge holding the inkjet printhead has a flexible circuit member with conductive traces permanently bonded at one end to the interconnect junctions and terminating at the other end at cartridge interconnect pads.
