Abstract
The invention provides a printing apparatus which can adjust printing position more accurately. The apparatus has a printing unit, a pattern printing unit to print a first pattern and a second pattern so as to form a third pattern, and an adjustment unit to perform an adjustment regarding position of dots to be printed by the printing unit based on an optical reflectivity of the third pattern. The second pattern is substantially the same as the first pattern and is shifted relative to the first pattern in a predetermined direction. The first and second patterns each include a plurality of patterns having different cyclic natures in the predetermined direction.
