Abstract
A print head comprising a nozzle plate having a plurality of nozzles extending therethrough, a piezoelectric bending mode actuator associated with each nozzle and connected with the respective nozzle so as to provide a plurality of independently actuatable nozzles, and a mount for, in use, connecting the nozzle plate to a liquid printer, wherein, in use, each nozzle can be driven at its resonant frequency such that motion of the driven nozzle causes liquid to be ejected only from the driven nozzle.

A print head comprising:
- a nozzle plate having a plurality of nozzles extending therethrough;
- a piezoelectric bending mode actuator associated with each nozzle and connected with the respective nozzle so as to provide a plurality of independently actuatable nozzles;
- and
- a mount for, in use, connecting the nozzle plate to a liquid printer, wherein, in use, each nozzle can be driven at its resonant frequency such that motion of the driven nozzle causes liquid to be ejected only from the driven nozzle;
- wherein the mount is stiffer than the combination of the nozzle plate and piezoelectric actuators.
