Abstract (en)

[origin: EP0516091A2] A system for driving the thermal head (10) of a dye thermal printer for controlling energizing time of heating resistors (11) by applying a drive pulse having a pulse width corresponding to a modulation density of an input data every time the data is input thereto, characterized in that the drive pulse having the pulse width corresponding to the modulation density is applied to the heating resistor (11) until the modulation density reaches a given modulation density and repetition pulses having a given interval are applied thereto when the modulation density exceeds the given modulation density so that the high speed printing can be realized compared with the conventional system by preventing the transfer film (30) from being crumpled. <IMAGE>
