Abstract:
1. An ink jet printing apparatus capable of making a print without providing a margin on edge portions of a printing medium by ejecting at least a first ink from a printing head to the printing medium and to the outside of the printing medium while moving a printing head capable of ejecting the first ink and a second ink onto the printing medium, comprising: an ink absorber that absorbs the first ink ejected to the outside of the printing medium and the second ink; an acquisition section that acquires information on accumulation amounts of the first ink at first and second portions of the ink absorber; and a control section that controls ejection of the second ink from the printing head such that the second ink is ejected to the ink absorber, onto which the first ink is ejected, in order to suppress accumulation of the first ink on the ink absorber, wherein the control section changes an ejection condition of the second ink such that an amount of the second ink ejected at the first portion of the ink absorber is larger than an amount of the second ink ejected at the second portion of the ink absorber, wherein the first portion of the ink absorber is outside of the printing medium in the moving direction of the printing head, and the second portion of the ink absorber is outside of the printing medium in the conveying direction of the printing medium, and wherein the ejection condition is changed even when an accumulation amount of the first ink at the first portion of the ink absorber is equivalent to an accumulation amount of the first ink at the second portion of the ink absorber.
