Method and device to reduce the size and cost of electronic printers used with portable personal computers by printing each page as a series of narrow bands across the width of the page. An information carrier such as paper is placed between a back electrode (9) and a screen or lattice-shaped control electrode matrix (3), both of wich are connected to voltage sources. Voltage sources connected to the control electrode matrix (3) at least partially open and close passages through the electrode matrix (3). Charged pigment particles attracted from a particle carrier (4) through open passages are deposited on the information carrier to form visible images. |
