Abstract: In an example of the disclosure, a priming lane and a non-priming lane are identified within an image frame to be printed by a printer. A line of molten wax is applied to the roller. The molten wax when cooled is to form a wax ridge upon the roller. The roller having the formed wax ridge is wetted with the primer. The wetted roller is rotated against the substrate to apply the primer. A first width of the wetted roller that does not include the wax ridge forms the priming lane upon the substrate. A second width of the roller that includes the wax ridge causes the primer to not transfer and thereby forms the non-priming lane upon the substrate.

The printed cathode comprises: a thermoplastic resin; and electrically conductive metal particles. Also described herein is a method of producing the printed photovoltaic cell and an ink set for use in the method.

Abstract: A printing apparatus has a photo imaging plate to be held at a first voltage having a first polarity, and an intermediate transfer member to receive an intermediate image from the photo imaging plate. The intermediate transfer member is to be held at a second voltage having a second polarity opposite to the first polarity. An electrically conductive member is disposed between the photo imaging plate and the intermediate transfer member.

Abstract: Example implementations relate to selectively deflecting substrates. One example implementation includes an apparatus to selectively lift a part of a substrate away from a transfer member when the substrate is advancing in a substrate coating system relative to the transfer member, such that, across a width of the substrate, a first part of the substrate is coated by the transfer member and a second part of the substrate, that is lifted by the apparatus, remains uncoated.
