Abstract

Light emitting diodes are optically coupled to a photosensitive material through fiber optics. Incoming data are used to determine the emission of the diodes so that the incoming information is printed and stored as shades of grey. Tone and contrast control are provided, and either positives or negatives may be printed. Very high speed operation, on the order of gigabits per second, is currently feasible.
