| 摘要 |
A print head for a column-sequential or row-sequential dot matrix printer which prints dots by electrically propelling droplets of ink onto a record comprising a manifold having an ink chamber communicating with a plurality of closely spaced generally parallel ink tubes; a pair of electrodes extends into each ink tube at diammetrically opposed positions to provide a current path through electrically conductive ink in the tube and a magnetic field across the ends of the tubes causes a droplet of ink to be propelled outwardly from each tube whenever the electrodes for that tube are energized.
