<p>A multiple nozzle ink jet print head in which a printed circuit board is utilized to hold a plurality of ink droplet ejection means (28) in the required pattern. The ejection means (28) extend through respective apertures (16) in the circuit board substrate (12) and is connected with a conductive coating (18) on one surface (10) of the substrate (12) common to all apertures (16), and with respective individual runs of conductive material (22) on the opposite surface (14) of the substrate, whereby each ink droplet ejection means (28) is selectively energizable through the conductive material for pulse-on-demand printing. </p> |
