There is provided a checking apparatus being capable of readily performing re-printing while reducing an amount of storage for storing print image data to be used for checking processing. A control method for controlling the checking apparatus includes reading an image printed on a sheet by a printing apparatus, storing image data to be compared with the image read by the reading unit in a storage unit, determining whether the image printed on the sheet by the printing apparatus is correct based on the image data obtained by reading the image and the image data stored by the storage unit, judging whether the sheet has been discharged, and controlling deletion of the image data stored in the storage unit based on a determining result and a judging result.
