In some metal paper printers the print head is moved along the line by stepping motor. Arranged on the axle of the stepping motor a timing disk 1 (Fig. 1) is provided which has a series of markings 2 towards the circumference. These markings are scanned and used for print-out control. For printers with a higher degree of resolution the print-out control pulses are to have a higher frequency than the motor advance pulses. For that reason the timing disk has fine markings 3 between markings 4 for the motor advance control.
