Abstract

In order to facilitate the making of thermal printers for portable payment terminals, for example, a heat sink is made. To this heat sink, there is fixed a print head comprising two protruding features, on which there abuts a pin of a paper feed roller. Furthermore, the assembly formed by the head and the heat sink is fixed to the frame of the printer by two elastic links reacting in different directions and countering the positioning of the roller. The paper feed roller is thus placed flat against the print head, thus giving homogeneous contact between the head and the paper and the efficient positioning of the roller with respect to the print head.
