Abstract: Printing on a document is done by moving a rotating shutter having a narrow slit, between the document and a rotating stencil having character apertures, and moving both past a print position in timed relation with an ink spray from a nozzle supplied with ink and air under pressure.

Abstract: Method and apparatus for generating a plurality of parallel droplet streams in a coating apparatus, such as an ink jet printing device, in which the streams break into droplets from fluid filaments at a uniform distance from issuing orifices. The streams issue from a pressurized chamber in which an elastic bending member is repetitively flexed by a plurality of parallel bending elements operated simultaneously to produce uniform bending throughout the effective length of said member to produce successive pressure disturbances within the supply chamber and induce varicosities of the same size and frequency in the issuing streams. This arrangement is able to enhance printing quality in an ink jet recorder by permitting maintenance of proper phase relationship between droplet formation and charging voltage.

Abstract: A character generator is connected to the charging electrode of an ink jet printer nozzle through a compensating circuit which modulates the charging voltage applied to each individual ink drop in accordance with the charges on one or more preceding drops in order to compensate for the capacitance effect of the preceding drops on said one individual drop.
