Abstract of the Disclosure A piezoelectric crystal is connected with a membrane and is energized to deflect or bend the membrane for ejecting droplets of ink from an ink supply. The energizing voltage pulses are timed to start and are of a duration whereby the return of the membrane to a normal position upon termination of the voltage pulses acts against the negative pressure wave in the ink supply for preventing excessive underpressure therein.
