Abstract
A piezoelectrically driven ink jet print head for ejecting ink droplets from an ink supply within the print head through a discharge channel onto a writing surface includes a shutter mechanism that may be electromechanically controlled during selected periods of time to seal the ink supply within the print head from the atmosphere and from a high speed laminar flow of air used to accelerate ejected ink droplets.
