Abstract
An electrostatic printer having electrodes which each are constructed as a needle arranged on a rotatable drum mounted for translatory movements. At the recording area the needle slides directly over the paper under pressure to cause the paper to be slightly pushed away. The width of the recorded track is identified by the contact surface area of the needle.
