Abstract

Improvements introduced in a printer for electrostatic recording, which has a common counter electrode and a system of electrodes of mutually isolated electrode circuits, between whose extreme faces there are grooves or discharge spaces in the possible printing places, being capable of disruptive discharge or the light discharge originated in the throats to produce a charge image on a record holder located between the counter electrode of the electrode system after the activation of the counter electrode, characterized in that means are provided to control the potentials in the counter electrode (1) and in the electrode system (2,3) in such a way that the surface charge density and/or the surface areas of the charge image points at the printing places of the record holder (8) are variable.
