Abstract (en)

[origin: EP0677391A2] The appts. (1) has a charge carrier source (2) that is connected to an anode (8) and a cathode (9) creating a circuit containing a control appts. The control appts. is connected between the anode and cathode at to zero volts. When a specific voltage level between the anode and cathode is produced, a plasma flow (10) is produced and a transfer of ions (11) occurs to be deposited on the surface of a substrate (12). The charge pattern is transferred as a colour image onto paper. A number of charge carriers are produced as a highly integrated element within a print head. <IMAGE>
