1. An inspection apparatus operable to inspect an image printed on paper, the inspection apparatus comprising:
a controller including one or more memories storing instructions and one or more processors configured to execute the instructions to:
perform first image processing that is not according to a type of the paper on image data used in printing the image;
store the image data for which the first image processing has been performed as a reference image;
determine whether a first reference image corresponding to the reference image, which is usable in a job to be inspected, is stored;
upon determining that the first reference image is stored, perform second image processing that is according to the type of the paper on the first reference image to convert the first reference image into a second reference image corresponding to the job;
obtain a scanned image by reading an image of paper on which printing has been performed according to a print job; and
perform processing for matching the obtained scanned image and the second reference image.
