ABSTRACT:
A printer comprising a supporting structure and a print disc having a curved peripheral surface with characters formed thereon. The print disc is mounted on the supporting structure for rotation about a rotational axis. Paper is moved over the peripheral surface in a direction generally parallel to the rotational axis, and one or more hammers cooperate with the paper and the characters for effecting printing on the paper. A guide generally conforms the paper to at least a portion of the curved peripheral surface as the paper is moved over the peripheral surface. This permits an entire line of characters to be printed and provides the paper with some rigidity against bending and an ability to extend generally vertically to permit the user to visually observe what has been printed. To eliminate noise during standby, the print disc is rotated through only one revolution in response to each print command.
