PROBLEM TO BE SOLVED: To provide an ink jet printer in which bubbles in the channel or the head section can be removed completely under initial steady state, possibility of bubbling is extremely low even under printing state and thereby highly accurate high defintion print can be ensured. SOLUTION: The ink jet printer comprises an ink supply section, a head section for ejecting ink supplied from the ink supply section to a matter being printed, and a channel interconnecting the ink supply section and the head section, wherein the ink supply section comprises a pressurizing means being used for attaining an initial steady state, a constant pressure supply means being used under print state, and means for switching ink supply between the pressurizing means and the constant pressure supply means. |
