Abstract
A printing apparatus includes an imaging apparatus, a carriage, and a processing section. A sensor in the imaging apparatus has a plurality of pixels placed in a row direction and a column direction in the form of a matrix. The imaging apparatus is disposed in the carriage so that the row direction of the sensor and the direction in which the plurality of nozzles constituting each nozzle row are placed become parallel. The processing section causes ink to be discharged from a nozzle row to be adjusted to print a test pattern. By using a two-dimensional scale as a reference in detection of landing deviation, the processing section detects the landing deviation caused by the nozzle row to be adjusted, according to the imaged test pattern.
