Abstract
A device for projecting ink droplets through a set of projection holes to print a pattern under selective electrical or light pulse control. A first plate formed with a large number of holes is placed in close proximity to the surface of the printing medium. A second plate a small distance from the first defines therewith a chamber in which the ink is locally heated by electrical current controlled by light selectively impinging on a photoconductive part of said second plate in register with each hole or each group of holes so as to form a pattern with constant or variable parts.
