Abstract: The deposition and drying out of ink on the front surface of a print head nozzle plate adversely affects the ejection of the ink droplets. The nozzle plate (12) of ink wettable material carries a coating (30) on its front surface on non-wetting material. Such arrangement provides a stable meniscus of the ink column in each nozzle (24) and prevents ink from depositing at the front surface around the nozzle orifice. The principal use is in an ink jet printer.

Abstract: Dot matrix printer including at least one print head (40) and driving means (54) for causing movement of the print head in side to side direction relative to a record medium (50) movable past the print head so as to enable the print head to print a line on the record medium. Prior art driving systems used for moving a print head in a side to side manner required considerable energy. In the present invention the driving system includes spring means (44, 46) operably connected with the print head and electrodynamic drive means (54) causing the spring means to oscillate at a frequency corresponding with the natural frequency of the assembly of spring means and print head so as to bring about oscillating motion of the print head in side to side direction. This arrangement reduces significantly the energy required for acceleration and deceleration of the print head.
