A printer comprising an impact device which is provided with an impact member which is electromechanically driven and whose position or speed is measured by means of a transducer in order to obtain a speed signal which is compared with a reference signal in a comparator. The signal output of the comparator is connected to a signal input of an electrical actuation device for driving the impact member, the actuation of the drive being terminated only after a stop signal has appeared on the signal output of the comparator. An adapted speed of the impact member is obtained in all circumstances in a printer in accordance with the invention.
