ABSTRACT:
Character rings mounted on a common shaft and having a plurality of circumferential character columns thereon, are opposed by a platen including recessed portions. A recessed portion faces non-printing character columns when the platen presses against one character column on each character ring for printing on paper. The platen translates laterally so that each character column on a character ring is printed in sequence. A single character selection and return mechanism serves all columns on a single character ring. A translating mask separates non-printing characters from the paper.
