Title: Electrostatic printing device with air cushion guiding

Abstract: An electrostatic printing device comprising a rotatable printing roller with stylus electrodes. In order to keep the distance of the images or of the recorded sheets small and the images themselves clear and pure, notably at the edges, the stylus electrodes are moved transversely of the longitudinal direction of the tape-like record carrier. The foil tape is at the same time continuously transported. Thus, the translatory movement of the printing roller supporting the stylus electrodes is eliminated.
