Abstract
A thermo transfer matrix printer has a print drum having over its entire periphery a first set of equidistantly spaced axially extending electrode lines, further having a second set of azimuthally extending electrode lines; the two sets of lines are separated through an electrical resistance layer such that an electrode line of the first set intersecting a line of the second set but being separated therefrom by the resistant layer is resistively interconnected at that intersection, thereby establishing a heatable matrix point; an ink dispensing station is disposed along the periphery of said drum for transferring over the entire length of the drum thermo ink and dyw to adhere to the outer periphery of the drum at heated points; and a platen drum is disposed adjacent to the transfer drum for urging a print medium against the transfer drum is a tangential line of printing.
