ABSTRACT:
A solid ink cartridge for a non-impact printer with emission of solid ink particles is disclosed. A rod of solid ink is spring-pressed in an insulating housing against an end wall with a nozzle therein. A pulsed high voltage applied between the ink rod and a counter-electrode (which can be behind a paper target) causes ink particles to be eroded from the rod and ejected through the nozzle onto the paper. The printer includes incremental line-feed paper movement, movement of printing devices as just described along the printing line, and selective control of the high-voltage pulsing such as to form characters by a dot matrix technique.
