Printing method and printing apparatus

A printing method of printing an image by a printing apparatus ejecting ink from a plurality of nozzles forming nozzle rows to form dots on a medium, wherein the printing apparatus repeatedly performs transportation of transporting the medium in a transport direction and movement of moving the nozzle rows in a scanning direction intersecting the transport direction,

• wherein coordinates of dots formed by nozzles of a nozzle row center portion and coordinates of dots formed by nozzles of nozzle row end portions are measured with respect to a ruled line printed in advance along the transport direction by ejecting ink from the plurality of nozzles, and an amount of deviation in the scanning direction among the coordinates is calculated, and
• wherein pixel data corresponding to the dots formed by the nozzles of the nozzle row end portions among pixel data indicating unit elements forming an image are shifted in the scanning direction according to the amount of deviation to perform printing.
