Abstract
The printer records images in the form of dots on electrical discharge-sensitive paper. Three groups of five styli are mounted on a rotor. The paper is in strip form and is fed continuously through a curved guide in a direction perpendicular to the plane of rotation of the rotor, so that the paper is wrapped part-way around the rotor as it moves past. Characters are formed from a 5 dot by 7 dot matrix.
