The described device effects printing by ejecting single droplets of dye from nozzles by piezoelectric means. The nozzles can be arranged in a dense array from which droplets are ejected, forming images (single- or multi-colored), as the printhead transverses the paper (serial printer) or the paper moves past the printhead (line printer/facsimile printer)- The essential features of this device are illustrated in Fig.1 and can be outlined as follows: The orifice nozzle consists of the following elements (Fig. 1): 1. dye cavity; 2. anode laminate; 3. cathode laminate; 4. piezoelectric transducer; 5. potting or casting compound; 6. orifice plate; and 7. dye supply channel from dye reservoir.
