Title: Apparatus for and method of ejecting ink of an ink-jet printer

Abstract: An apparatus for ejecting ink in an ink-jet printer that ejects the ink outof the openings on the nozzle plate only by the vapor pressure of bubblesof gas generated on the surface of individual electrodes due to theelectrolysis of the conductive ink by applying positive voltage to theindividual electrodes wetted with the ink and negative voltage to a commonelectrode, without using a heater for heating the ink and a plurality ofprotective layers to protect the internal electrodes, thereby making itpossible to realize a high speed printing operation for high frequency bya short impulse duration with low voltage.
