Abstract
A non-impact printing method wherein pulsed light is transmitted through a mask containing enlarged characters. The characters are optically reduced and are focused on a document in back of a heat-sensitive or thermal magnetic ink ribbon. Heat energy projected by the pulsed light causes ink transfer from the ribbon onto the paper.
