ABSTRACT:
A printer has a printhead comprising an array of nozzles. A nozzle arrangement has an ink chamber formed in a wafer substrate and one wall of the chamber having at least one flexible portion. The ink ejection port is formed centrally on the wall with a rim surrounding it. The wall is adapted to move independently of the rim such that upon heating of the flexible portion of the wall, the wall bends into the ink chamber forcing ink therein out through the ejection port.
