In ink jet printers it is mandatory that when the system calls for a shut off, the ink supply being fed from the nozzle be quickly terminated so that no dribbling of the ink occurs onto the adjacent machine parts. Moreover, it is desirable that there be no negative pressure pulses which permit air to enter into the nozzle to effect ink drying and the like.
