ABSTRACT:
A printer has a plurality of nozzles formed on a substrate. Nozzle chambers receive an ink and a nozzle actuator receives drive signals from drive circuitry formed on the substrate. Upon actuation, the nozzle actuators move to eject ink from the nozzle chamber. Wicking of fluid across the substrate is prevented by a recess in the nozzle chamber walls.
