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.

Thermal printing apparatus includes a magnetic core having a gap, an electromagnetic coil mounted on the core for generating an electromagnetic field in the core and through the gap, a rotatably mounted cylindrical thermal print head having type characters on its periphery and located partially within the gap in the magnetic core, and a mechanism for rotating the print head to locate a selected type character in printing position in cooperative relation to a pressure element. The magnetic field generates circulating currents in the print head for heating it to a temperature necessary for causing heat-sensitive ink to be transferred from a ribbon to a record medium, both of which are positioned between the print head and the pressure element.

A recording apparatus having multiple recording devices, each recording device being associated with a separate document feed path, in order to provide simultaneous recording on more than one document for the purpose of increasing effective document recording speed. The recording apparatus also includes driving mechanism for driving the documents along the feed paths, selection means for selecting an appropriate document feed path for each document which is introduced to the recording apparatus, and control means for controlling the recording devices, the driving mechanism and the selection means.
