ABSTRACT:
The present invention is a printhead for ejecting fluid droplets. The printhead includes a chamber member defining a chamber. The chamber member has a chamber volume associated therewith. The chamber member defines an orifice and a fluid inlet through which fluid flows to the chamber. Also included is a heating member for heating fluid within the chamber. The chamber ejects a fluid droplet having a volume equal to the chamber volume in response to activation of the heating member.
