ABSTRACT:
An ink jet printing device includes a substrate that defines a plurality of ink supply passages. Drive circuitry is positioned on the substrate. A plurality of nozzle chamber structures is arranged on the substrate. Each nozzle chamber structure defines a nozzle chamber and an ink ejection port in fluid communication with the nozzle chamber. Each nozzle chamber structure has a wall that incorporates a number of actuators. Each of the actuators is displaceable, on receipt of an electrical signal from the drive circuitry, into and out of the nozzle chamber to eject ink from the ink ejection port.
