ABSTRACT:
A method and apparatus for electronic printing onto a transparent, translucent or opaque substrate. The substrate is of a type which will support an electrostatic image on a surface thereof and which does not have a conductive ground plane affixed to or deposited on its rear surface. The method includes the steps of applying a selected charge pattern to the surface of the substrate to form an electrostatic latent image thereon, applying an electrostatic toner to the surface via a donor member to provide a toner image thereon and fixing the toner. The apparatus includes a charging arrangement to deposit a selected charge pattern onto a surface of the substrate, a donor member arrangement to transfer toner from a toner source to the surface of the substrate and a fixer arrangement to fix the toner to the surface of the substrate.
