A high speed non-impact printer including an array of selectively operable light sources. A closed looped band moving across said array at a high linear rate of speed is provided with a plurality of small openings, each associated with one of the light sources. Said sources are selectively energized in a predetermined manner to collectively produce a row of dots and/or lines of varying length which, together with successive rows of dots, cooperate to produce a graphic pattern or a row or rows of characters of the dot matrix type, for example. The design of the system, together with the use of the light sources, totally eliminates the need for a complex optical system, employed in conventional high speed non-impact printers.
