Abstract

A printer for optionally printing the front side and back side of a band-shaped recording medium has a feed device to move the recording medium from the front side printing and fixing stations to a turn-overs station where it is turned over and returned to the printing and fixing station to print the back side. Pairs of driven rollers are provided in the paper channel to move the recording medium, wherein the frictional forces on the recording medium by the rollers can be set. The rollers are reversible and can also be swivelled out for certain printing modes and recording media sizes. Automatic threading of the recording medium is provided.
