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.
