Apparatus and method for driving recording head for ink-jet printer

摘要

An ink-jet printer comprising: a droplet outlet orifice through which an ink droplet is ejected; an ink chamber for supplying ink to the outlet orifice; pressure generating means for generating a pressure for ejecting the ink droplet through the outlet orifice by changing a volume of the ink chamber through displacement thereof; and ejection control means for initially displacing the pressure generating means in a direction of contracting the ink chamber to cause the ink droplet to be ejected through the outlet orifice and then further displacing the pressure generating means in the direction of contracting the ink chamber.
