Abstract
Method and device for high quality printing with substantially reduced cross-coupling while reducing the manufacturing cost of printers that use a matrix of individual control electrode units by connecting individual control electrode segments in series to reduce the number of electronic drive circuits. An information carrier such as paper is placed between a back electrode and an electrode matrix both of which are connected to voltage sources. Voltage sources connected to the control electrode unit matrix at least partially open and close passages through the electrode matrix; charged pigment particles attracted from a particle carrier through the open passages are deposited on the information carrier to form visible images.
