ABSTRACT:
A printing head for an ink jet printer having a plate-shaped part with opposite large surfaces provided with spaced grooves which, when assembled, form pressure chamber channels. The plate-shaped part has a recess in a side thereof whereby a second plate is inserted in the recessed position having channels which are aligned with and correspond to the pressure chamber channels of the first plate. The channels in the second plate continuously taper toward the outlet thereof to form fine capillary tubes, the latter being connected alternately to channels in one large surface and the other large surface of the first plate. The sealing of the plates is on one surface only.
