ABSTRACT:
An ink jet print head has a plurality of nozzles arranged in a vertical line at the printing end and connected by respective ink channels to pressure cavities in a circular arrangement at the ink supply end. The pressure cavities are supplied from an intermediate chamber contained in the print head and formed in a thin elongated shape and positioned generally in a plane parallel with the line of the nozzles. The construction of the print head compensates for acceleration and deceleration forces which are induced in the ink due to movement of the print head in the horizontal direction or perpendicular to the plane of the nozzles.
