Abstract
A pressure applying element, a sheet to be printed, and an ink ribbon, an interchangeable form carrying printing indicia, and a pressure absorption plate are arranged in vertical sequence to be pressed together by the pressure applying element in the printing process whereby the pressure absorption plate absorbs the applied pressure, the ink ribbon being wound on a delivery spool and a wind-up spool mounted for rotation in a cassette housing, the cassette housing forming a guide delivering ribbon from the delivery spool about one free edge of the pressure absorption plate, transversely across the pressure absorption plate in spaced relation thereto, about the opposite free edge of the pressure absorption plate and to the wind-up spool, the cassette being removeable from and insertable in the press in a direction parallel to the spool rotational axes and the free longitudinal edges of the pressure absorption plate.
