1. A method of driving a hybrid inkjet printing apparatus, the method comprising:
applying an electrostatic voltage to ink contained in a nozzle; applying a waveform piezoelectric voltage to a piezoelectric driving device in order to resonate the ink contained in the nozzle; and applying an ejection piezoelectric voltage to move the ink in the nozzle in a first direction in which the ink is ejected so as to eject the ink, wherein the applying of the waveform piezoelectric voltage to resonate the ink includes,
applying a first waveform piezoelectric voltage to move and maintain the ink in the nozzle in the first direction, andapplying a second waveform piezoelectric voltage to move the ink in a second direction opposite to the first direction, and wherein the ejection piezoelectric voltage is a pulse voltage having an absolute value greater than an absolute value of the waveform piezoelectric voltage.
