and at least one memory storing executable instructions, which when executed by the one or more processors, cause the inspection system to: receive a print job including a sheet attribute and image data, the sheet attribute indicating whether a sheet is a pre-printed sheet on which information has been printed before printing in accordance with the print job is performed; register a reference image based on the received image data in a case where the sheet attribute does not indicate the pre-printed sheet; and determine whether an image that is printed on the sheet in accordance with the print job and that is read is normal based on the registered reference image, wherein, if the sheet attribute indicates the pre-printed sheet, control is performed so as not to register the reference image based on the received image data. ### Claim 2 (depends on 1) The inspection system according to claim 1, further comprising: a display, wherein, if the sheet attribute indicates the pre-printed sheet, unavailability of the pre-printed sheet is displayed on the display. ### Claim 3 (depends on 1) The inspection system according to claim 1, wherein the reference image is generated by performing a layout process for printing to the image data. ### Claim 4 (depends on 1) The inspection system according to claim 1, wherein a printing apparatus conveys the sheet on which the image is printed to an inspection apparatus, and the inspection apparatus inspects the image on the sheet conveyed from the printing apparatus. ### Claim 5 (depends on 1) The inspection system according to claim 1, wherein, if the sheet attribute indicates the pre-printed sheet, control is performed so as not to select a paper cassette to which the pre-printed sheet is fed. ### Claim 6 A method of controlling an inspection system, the method comprising: receiving, by a printing apparatus, a print job including a sheet attribute and image data, the sheet attribute indicating whether a sheet is a pre-printed sheet on which information has been printed before printing in accordance with the print job is performed; registering, by an inspection apparatus, a reference image based on the received image data in a case where the sheet attribute does not indicate the pre-printed sheet; and determining, by the inspection apparatus, whether an image that is printed on the sheet in accordance with the print job and that is read is normal based on the registered reference image, wherein, if the sheet attribute indicates the pre-printed sheet, control is performed so as not to register the reference image based on the received image data. ### Claim 7 (depends on 6) The method according to claim 6, wherein the inspection system includes a display, and wherein, if the sheet attribute indicates the pre-printed sheet, unavailability of the pre-printed sheet is displayed on the display. ### Claim 8 (depends on 6) The method according to claim 6, wherein the reference image is generated by performing a layout process for printing to the image data. ### Claim 9 (depends on 6) The method according to claim 6, wherein the printing apparatus conveys the sheet on which the image is printed to the inspection apparatus, and the inspection apparatus inspects the image on the sheet conveyed from the printing apparatus. ### Claim 10 (depends on 6) The method according to claim 6, wherein, if the sheet attribute indicates the pre-printed sheet, control is performed so as not to select a paper cassette to which the pre-printed sheet is fed. ### Claim 11 (depends on 6) A non-transitory computer-readable medium storing a program including instructions, which when executed by one or more processors of the inspection system, cause the inspection system to perform the method according to claim 6. ### Claim 12 A printing apparatus comprising: one or more processors; and at least one memory storing executable instructions, which when executed by the one or more processors, cause the printing apparatus to: receive a print job including a sheet attribute and image data, the sheet attribute indicating whether a sheet is a pre-printed sheet on which information has been printed before printing in accordance with the print job is performed; and if the sheet attribute does not indicate the pre-printed sheet, transmit a reference image to an inspection apparatus based on the received image data, wherein, if the sheet attribute indicates the pre-printed sheet, control is performed so as not to transmit the reference image based on the received image data to the inspection apparatus. ### Claim 13 An inspection apparatus comprising: one or more processors; and at least one memory storing executable instructions, which when executed by the one or more processors, cause the inspection apparatus to: receive image data from a printing apparatus, wherein the image data is included in a print job including a sheet attribute indicating whether a sheet is a pre-printed sheet on which information has been printed before printing in accordance with the print job is performed; register a reference image based on the received image data in a case where the sheet attribute does not indicate the pre-printed sheet; and determine whether an image that is printed on the sheet in accordance with the print job and that is read is normal based on the registered reference image, wherein, if the sheet attribute indicates the pre-printed sheet, control is performed so as not to register the reference image based on the received image data.
