Abstract
Beneath its line of heater points, the print head includes a film of thermoresistive material which is used for sensing temperature in the proximity of the heater points, thereby making it possible to obtain a signal which can be used quickly in regulating the quantity of energy delivered to each heater point, thereby making it possible to operate the points at a higher rate because they are subjected to excitation which is regulated.
