ABSTRACT OF THE DISCLOSURE A cross hammer type dot printer comprises a rotary drum having an outer peripheral surface formed with a plurality of projections extending along its lon- gitudinal axis, and a printer head disposed in front of the drum and movable in a direction which is perpendicular to the direction in which a recording medium is fed. The printer head faces the drum in a way in which it substan- tially crosses the projections on the drum, and includes an electromagnetically operable printing hammer. The projections are displaceable vertically relative to the printing hammer upon rotation of the drum, while the print- ing hammer is horizontally displaceable relative to the projections upon movement of the printer head, so that when the hammer strikes against the projections, dots are printed where they cross each other. The printer head of this invention is suitable for use in such a cross hammer type dot printer. It can be made of a small number of parts, and is small.
