Abstract
A printer head, for an ink-on-demand type ink-jet printer, squirts ink droplets onto a printing medium. The printer head includes a nozzle for delivering the ink droplets and a passage for supplying ink from an ink tank. The ink is pressurized in accordance with an electric signal which commands the delivery of the ink droplets. Fluid control valves are deformed under the action of the ink pressure.
