Abstract (en)
[origin: WO9507185A1] An ink jet print head with a closest spacing in the vertical matrix direction of p and with a closest spacing in the horizontal matrix direction of q, has parallel ink channels, piezoelectric side walls, nozzles, and a common ink manifold. The channels are arranged in N groups which are successively enabled for droplet ejection and the head is inclined at an angle beta to the vertical matrix direction given by formula (I) where i is a positive integer. This provides an increase in the operating frequency and avoids the need for offsetting the nozzles of one group with respect to another.
