Abstract
In an embodiment of the present invention, even though there is a print shift due to a gap between a nozzle in an upstream side and a nozzle in a downstream side of a printhead, a printing apparatus capable of precisely adjusting a slant of a printhead with respect to a conveyance direction in a nozzle surface of the printhead is provided. According to the embodiment, two adjustment patterns are printed at two different carriage speeds, respectively, and a print shift due to a slant of the nozzle surface of the printhead with respect to a conveyance direction of a print medium is adjusted based on these two print results.
