and in the vibrating plates 42 as previously stated and as is clear from the above descriptions in an ink jet printer head in accordance with the invention a plane perpendicular to the longitudinal axis of the ink nozzle and tangent to the meniscus of the ink layer at the point of intersection of said longitudinal axis is made substantially parallel to the front face 47 where the nozzles discharge accordingly the ink droplets are not deflected from a linear parallel extension of the longitudinal axis of the nozzle thus an ink jet printer head in which no dot shift is caused and in which printing is carried out with a high density and high print quality is provided an alternative embodiment of a multi row ink jet printer head in accordance with the invention is shown in fig1 in this ink jet printer head a recess 70 is cut into the central portion of the front face 47 of the main substrate 41 the width of the recess 70 is such that the remaining thickness t7 at the nozzle 45 substantially equals the thickness t6 of the vibrating plate 42 which forms the outer wall surface of the nozzle.
