Abstract
An electrostatic printer for printing images on an electrostatic recording medium. The electrostatic printer includes an elongated electrode and a back electrode. The back electrode is spaced from the elongated electrode to define a gap therebetween. The gap, defined by the elongated electrode and the back electrode, is adapted to permit the passage of the electrostatic recording medium in a predetermined direction and is effectively reduced at a given point on the elongated electrode. The elongated electrode is displaceable relative to the back electrode so that the point on the elongated electrode which then defines the effectively reduced gap is displaced laterally of the direction of passage of the electrostatic recording medium in response to the displacement of the elongated electrode. A voltage is selectively applied between the elongated electrode and the back electrode for effecting printing on the electrostatic recording medium in registration with the point on the elongated electrode then defining the effectively reduced gap.
