  • Ink jet printer
    Patent number: 6244684
    Abstract: An ink jet printer of the present invention includes a recovering device for repeating, at the time of recovery from defective ink ejection, the suction of ink a plurality of times while varying a suction pressure acting on the ink. This successfully reduces the amount of bubbles and reduces the number of times of suction to thereby obviate the wasteful consumption of ink at the time of recovery. A printing method practicable with the ink jet printer and a storage medium storing the printing method are also disclosed.
