ABSTRACT:
Apparatus for directing a jet of fluid at a target to deposit a desired image thereon. The apparatus employs a nozzle with a pointed nozzle nib, a supply of fluid for the nozzle, and a pressure regulator controlling the pressure of the fluid at the nozzle upstream of the nib. The jet of fluid is accelerated from the nozzle nib and caused to flow to the target by the creation of an electric field in the region between the nozzle and the target. The fluid jet is substantially prevented from breaking up into droplets during flight by a combination of techniques so that the fluid flows to the target as a solid liquid filament or as a stream of mist-size droplets which are so small and so closely spaced that they behave like a solid liquid filament. The amplitude of the fluid flow is continuously modulated in response to an information signal by fluid surface pumping action or other means to produce the desired fluid image on the target.
