An impulse ink jet apparatus provides bar coding using one or more ink jet chambers having a plurality of orifices in each chamber. A transducer is coupled to each chamber for ejecting droplets from each of the plurality of orifices in the chamber in response to the state of energization of the transducer.

Method and apparatus for printing with ink jet chambers utilizing a

Impulse ink jets utilizing elongated transducers which expand and contract along the axis of elongation are formed by plates lying in planes parallel with the axis of elongation. The plates containing the chamber also include a drive portion for coupling the transducer to the chamber where the drive portion is supported by struts which extend to a support means also formed by the plates.

Font of type

A divergent ink jet nozzle array is made by forming by photochemical means suitably shaped polymeric posts on a conductive substrate, then electroplating a metallic material around the posts. The metallic material is stripped from the substrate, and the posts dissolved providing a well-defined ink jet array.
