Dependent claims

An apparatus for printing on a substrate, comprising:

(a) a nozzle capable of emitting a stream of individual droplets of liquid toward the substrate;
(b) a droplet charging section capable of providing an electrical charge to the droplets;
(c) a pair of electrically conductive deflecting plates for creating an electrical field capable of deflecting the droplets to a desired location of the substrate, wherein each of the plates has an interior side facing the path of the stream of individual droplets of liquid, and wherein an outer layer of the interior side of at least one of the deflecting plates is a dielectric.

Dependencies are inferred from the claim text.
