1. A printing apparatus, comprising:
a transport unit configured to transport a fabric formed with a first pattern in a transport direction;
an imaging unit configured to image the fabric transported by the transport unit;
a printing unit configured to perform printing on the fabric transported by the transport unit;
a pattern correction unit configured to change a mutual positional relationship among a plurality of divided pieces of first image data obtained by dividing first image data representing the first pattern to generate corrected first image data having a center made up of four corners of the first image data;
a pattern extracting unit configured to compare the corrected first image data with second image data generated by imaging the fabric by the imaging unit to extract a pattern region corresponding to a second pattern represented by the corrected first image data from the second image data;
a printing image generation unit configured to arrange third image data representing an image to be printed overlaid on the first pattern so as to match a region having, as four corners, centers of a plurality of the pattern regions extracted to generate printing image data; and
a printing control unit configured to cause the printing unit to print the printing image data on the fabric.
