ABSTRACT:
An inking device for a thermal printer includes a hollow cylindrical inking roller made of a porous material and having a bladed wheel at the bottom of the cylindrical inking roller.

A hollow cylindrical receptacle, for storing thermally fusible ink, is surrounded by the inking roller and has an opening at the top and apertures at the bottom for the egress of ink. A heater is provided for heating the receptacle. The receptacle has an axis deviated from the axis of rotation of the inking roller.
