ABSTRACT:
Pressure transients are used to produce motion for high speed printing of DOTS; in a first embodiment each printing element in an array of printing elements has the form of an angled rigid tube sealed at the ends; one end is fixed, the other end is free to move; the tube is filled with suitable fluid and has two electrodes associated with it and the fluid; a spark across the electrodes on demand produces a pressure transient by expanding the fluid, in turn tending to straighten or otherwise suitably deform the angled tube in a direction advancing the free end for printing; in a second embodiment employing ink as the fluid, a ball point pen arrangement dispenses ink as the second end advances on spark actuation.
