A thermal printer head has an insulator base with a plurality of linear recesses in the surface thereof, and heat generator elements embedded within the recesses in such a way that the areas of the surface of the base between the recesses are adapted to contact heat sensitive paper during a printing operation, so that the heat generator elements are protected against wear. The base can be a flat plate or a cylinder, and can have rear resistive films in the recesses over the heat generator elements.
