ABSTRACT:
A thermally activated liquid ink printing head has a plurality of orifices in a wall of an ink reservoir, the ink retained in the orifices by surface tension. Electrical heating elements heat the ink in the orifices, the ink being caused to pass across to a paper sheet positioned adjacent to the orifices. The orifices may extend in a line across the head or may be in other predetermined patterns, such as for printing alpha-numerics a character at a time. The ink may be completely or partly vaporized. The heating current may flow through the ink.
