BF&N 6594 JET DROP PRINTER ABSTRACT OF THE DISCLOSURE A jet drop printer for depositing drops of print fluid on a moving print medium includes an elongated fluid reservoir with an orifice plate extending the length of the fluid reservoir and communicating therewith. The orifice plate defines a plurality of orifices from which filaments of print fluid emerge. The orifices are positioned along an orifice line on the orifice plate which is non-parallel with respect to the center line of the orifice plate, which center line extends in the direction of elongation of the reservoir. A stimulator induces bending waves in the orifice plate which travel along the orifice plate in a direction parallel to the center line. Substantially uniform break up of the filaments into drop streams occurs as the bending waves impart substantially the same amplitude of mechanical stimulation to each of the fluid filaments. The drops in the drop streams are selectively charged and deflected such that selected ones of the drops are directed to strike the print medium and others of the drops are directed to a catcher.
