Abstract

The invention relates to a method for controlling the amount of energy from a printer head in a thermo-printer. The appropriate amount of energy for obtaining the best possible print quality with a certain printing material is controlled through calculating the amount of energy required as a function of the printing speed of the printer, over the full range of printer speed, and of the characteristic printing material data. The printing speed is continuously variable within the complete printing speed range of the printer. Characteristic data for the printing material are classified for magnitude and may be given as an offset relative to a reference material, or as absolute values.
