Abstract (en)
A method for calibrating the heating elements in a thermal head of a thermal printing system, containing initial configuration settings, at least for the highest value of resistance of a heating element (Rmax) or the largest value of power which can be dissipated in each heating element (Pmin), and comprising the steps of activating each heating element under simulated operational conditions taking into account said initial configuration settings, measuring the current through each heating element and calculating the resistance or the dissipated power of each heating element, to obtain new values for Rmax or Pmin. <IMAGE>
