Abstract: A method for managing printing of data by a thermal printer. The thermal printer includes a thermal print head. The thermal print head has a plurality of points, each point having an effective resistance rd, and is powered by a power source. The method includes the following actions: measuring a voltage U given by the power source of the thermal printer; measuring an internal resistance ru of the power source; and computing a duration t for heating a number n of points as a function of the voltage U of the power source, the internal resistance ru of the power source, at least one effective resistance rd of at least one point corresponding to a dot to be printed for the printing of the data and as a function of at least one value of parasitic resistance rp of at least one element of the thermal printer.
