1. A device for positioning a printhead in an opening of a frame in a predetermined position with respect to a plane extending in the direction of the plane of the frame (plane X-Y), wherein the printhead includes a first spherical segment provided on a first side and a second spherical segment provided on a second side situated opposite the first side and the frame comprises a positioning means which, after placing the printhead, exerts a force with a component in the radial and tangential direction on the printhead at the first spherical segment, the tangential component reaching a minimum in the situation in which the printhead is situated in the predetermined position, and a recess in which the second spherical segment is pressed by the positioning means.
