A printing apparatus that can print an image on a medium having a disc shape, the printing apparatus comprising: determination means configured to determine whether or not predetermined processing in accordance with the disc shape has been executed on the image; execution means configured to execute the predetermined processing on the image in a case where the determination means determines that the predetermined processing has not been executed on the image; and printing means configured to print the image on which the predetermined processing has been executed by the execution means on the medium having the disc shape, wherein, in a case where the determination means determines that the predetermined processing has been executed on the image, the execution means does not execute the predetermined processing on the image and the printing means prints the image; further comprising: reception means configured to receive the image from an information processing apparatus, wherein the image is a JPEG file, and the determination means determines whether or not the predetermined processing has been executed on the image based on whether or not EXIF information of the JPEG file includes predetermined information; wherein the predetermined processing is mask processing of rewriting a pixel value corresponding to an area where the printing is not performed in the image to a predetermined pixel value indicating that the printing is not performed by the printing means; and wherein, if the EXIF information does not include the predetermined information, the determination means analyzes the pixel value corresponding to the area where the printing is not performed in the image to determine whether or not the predetermined processing has been executed on the image. determination means configured to determine whether or not predetermined processing in accordance with the disc shape has been executed on the image; execution means configured to execute the predetermined processing on the image in a case where the determination means determines that the predetermined processing has not been executed on the image; and printing means configured to print the image on which the predetermined processing has been executed by the execution means on the medium having the disc shape, wherein, in a case where the determination means determines that the predetermined processing has been executed on the image, the execution means does not execute the predetermined processing on the image and the printing means prints the image; reception means configured to receive the image from an information processing apparatus, wherein the image is a JPEG file, and the determination means determines whether or not the predetermined processing has been executed on the image based on whether or not EXIF information of the JPEG file includes predetermined information; wherein the predetermined processing is mask processing of rewriting a pixel value corresponding to an area where the printing is not performed in the image to a predetermined pixel value indicating that the printing is not performed by the printing means; and wherein, if the EXIF information does not include the predetermined information, the determination means analyzes the pixel value corresponding to the area where the printing is not performed in the image to determine whether or not the predetermined processing has been executed on the image.
