Heat applying print head.

摘要

A plurality of arrays of heating elements, forming printing zones (2), are arranged separated from each other a predetermined distance (SL) on a substrate (3) along a direction (X) transverse the media transport direction (Y). The heating elements in each zone (2) are arranged parallel to the transport direction (Y). The head (1) is swept back and forth relative to print line (17), a distance of SL. Releasable backing means are formed by rollers and each printing zone (2) is associated with a roller. The backing means is moved together with the head (1) for urging the print media against the thermal transfer ribbon and the latter against the multi-zone thermal print head.
