Abstract

In a method and thermotransfer printing device for setting the speed of a relative movement between the print head and a recording medium during a printing procedure in the thermotransfer printing device, in particular for setting the transport speed of a mail piece in a thermotransfer printing franking machine, the heat energies required for the generation of a predeterminable print image are calculated for the individual heating elements of the print head from start value that has been established for the desired speed. It is subsequently computationally checked whether the respectively calculated heat energy can be emitted at the respective heating element in a first time interval predetermined by the start value of the desired speed and a predeterminable remaining time. If so, a printing procedure follows in which the beginning of the printing procedure ensues using the end value of the desired speed.
