The drive motors are of identical design and cooperate with drive guide rollers arranged exteriorly of the printing area. Stepping motors preferably are employed as the drive motors and arranged with a displacement by half a step and can be alternately driven, so that one of the two stepping motors always functions in optimum torque range.
