ABSTRACT "Printer" A printing apparatus is provided which consists of an ink applicator spaced from the printing substrate. The printing mark is made upon the substrate by a fine stream or spray of ink, which stream or spray is provided electro- statically. An electrical field is established between the substrate and the applicator and the ink is drawn towards the substrate where it forms a spray of electrically charged droplets. The applicator of the invention consists of a nozzle having an extending porous wick which allows for improved flow of ink and more precise and uniform application without blurring.
