1. A printing method of printing a first image and a second image on a printing object, by using a print head, while changing a relative position and a relative attitude of the print head relative to the printing object, the printing method comprising:
a first printing step of printing a first print image on the printing object by using the print head, the first print image being obtained by forming an unprinted region in the first image;
a detecting step of detecting the unprinted region by using a sensor provided on the print head, at the relative position and the relative attitude of the print head used when the second image is printed;
an adjusting step of adjusting the relative position and the relative attitude of the print head in a manner so that the second image adjoins the first image, based on the unprinted region that has been detected; and
a second printing step of printing a second print image on the printing object by using the print head, the second print image including the second image and a partial image to be printed in the unprinted region.
