(54) PRINTING APPARATUS AND PRINTING METHOD


(57) A printing mechanism unit that forms a first printing area in a recording medium which is transported by ejecting first ink onto a first path in a direction crossing a transport direction of the recording medium, forms a second printing area in the recording medium by ejecting second ink onto a second path different from the first path, and thereby forms an image which is configured with the first printing area and the second printing area; a pass analysis unit that decides a first ejection position of the first ink in the first path and decides a second ejection position of the second ink in the second path, when the image is formed; and a correction determination unit that performs ejection position change correction in which the first ejection position is changed such that the first ink is ejected onto the second path and the second ejection position is changed such that a part of the second ink is ejected onto the first path, are provided.
