A method and device to enhance the printing quality of direct electrostatic printers which utilize an electrode array and electrical signals to generate an electrical field to cause toner particles to be deposited directly onto plain paper to form visible images. The invention relates to an improvement to dynamically position and maintain a desired distance between the electrode array and the surface of the charged particles on the particle carrier.
