Abstract
A multi-channel array, pulsed droplet ink jet printer comprises a plurality of channels each communicating with a respective nozzle. A side wall of each channel is formed as a shear mode piezo-electric actuator. Electrodes applied to the actuators enable electric fields to be applied such that the actuators move laterally in the direction of the field to change the liquid pressure in the channels for effecting droplet ejection through the channel nozzles. The actuators can be made in two parts so as to deform, in cross section, to a chevron formation.
