[origin: US4578686A] A writing head for an ink printing device characterized by piezo-electric drive elements being formed by piezo-electrical laminae having cut edges shaped to produce a discharge opening in communication with an ink chamber which is separated from an ink supply channel by a choke channel. The laminae are arranged with spacer elements in a stacked arrangement to form the writing head with a plurality of discharge openings which can individually discharge droplets of ink.
