Abstract: A plurality of arrays of heating elements, forming printing zones, are arranged separated from each other a predetermined distance (SL) on a substrate along a line (X) transverse the media transport direction (Y). The heating elements in each zone are arranged parallel to the transport direction (Y). Mover elements sweep the head back and forth relative to print line, a distance of SL. Releasable backing element is formed by rollers and each printing zone, the length of which is SL, is associated with a roller. The backing-rollers are moved together with the head for urging the print media against the thermal transfer ribbon and the latter against the multi-zone thermal print head.

Abstract: In a thermal printer the transfer ribbon such as one having sets of transverse color stripes is guided over of a ribbon support which carries the heat applying print head. The ribbon support is movable relative to the paper by an eccentric to move the ribbon into and out of contact with the paper. A support beam and a guiding roller are provided immediately behind print area to guide the ribbon away from the paper path in an angle of more than 45 degrees. This assures a separation of the ribbon from the paper essentially normal to its surface, thus avoiding shear upon relative movement between paper and ribbon and negates the need for a relatively bulky ribbon carrier material.
