Abstract:
A printing apparatus for ejecting ink droplets from an ink ejection means onto a print medium to form an image, the printing apparatus comprising:generation means for generating detection pattern data to detect an ink ejection deviation, the ink ejection deviation being a deviation of a landing position of the ink droplets ejected on the printing medium by the ink ejection means; detection means for detecting the deviation of the landing position based on the detection pattern data; distance adjusting means to change a distance between the ink ejection means and the print medium; and control means to set a plurality of different distances by controlling the distance adjusting means, wherein the control means controls the distance adjusting means such that in a case where a detection pattern is formed in order to detect the landing position of ink droplets, the distance between the ink ejection means and the print medium is set to a second distance which is greater than a first distance for performing normal printing.
