Abstract
A direct electrostatic printing device and method for printing an image to an information carrier with increased density harmonization. By continuously keeping track of the amount of pigment particles each aperture has available and thereafter using this information and the desired print density to control the control electrodes of the individual apertures, a harmonization of the printed density from different apertures is attained.
