What is Electrophotographic Printing (E.P.)?

Electrophotographic Printing is a printing process that uses electrical charges, or ionized charges, to collect or repel particles from areas to be printed. The colorant is arranged on a printing cylinder by charging or discharging regions of the cylinder’s surface, or the colorant may be guided to areas of the printing cylinder by electrical fields around the printing cylinder. In either case, the image elements are then transferred to the printed surface by some combination of pressure and heat.  A method of this type was widely marketed as “xerography” by Edwin Land and the Xerox Corporation. More recently many variants on Xerox original proprietary methodology have been deployed for use in “digital presses”.
