ABSTRACT:
A printing apparatus is provided which utilizes rolling pressure contact for printing, and includes a plurality of sets of serially arranged character elements mounted for movement on the external surface of a printing drum. Movement of the sets to place a desired character into printing position is accomplished by controlling the speed of a motor driving a pulley connected by cable to a given character set, relative to the speed of a motor driving the printing drum in rotational movement.
