ABSTRACT:
This invention provides an ink mist type high speed printer comprising a first electrode and a second electrode between which a high voltage is applied, and an aperture board disposed between the first and second electrodes and adapted to selectively control passage of the ions generated from the second electrode, wherein a stream of ink mist is passed between the aperture board and first electrode so that the ions which have passed the aperture board will selectively charge the ink mist particles to let the charged ink mist particles deposit on a recording paper placed between the ink mist and first electrode to thereby print a desired dot matrix character. The first electrode is divided along its length into plural segments such that the respective segments may be separated individually from the aperture board, and the width of the first electrode is determined in correspondence to the width of the recording paper while controlling the width of the first electrode opposed to the second electrode so as to eliminate the possibility of deposition of ink mist on the aperture board.
