1. A printing system comprising a printing apparatus and an inspection apparatus, the inspection apparatus comprising:
at least one processor; and
at least one memory,
wherein when a program stored in the at least one memory is executed by the at least one processor, the program causes the at least one processor to function as:
a receiving unit that receives a scanned image obtained by reading along a conveying path a sheet on which an image has been formed;
an inspection unit that performs inspection of the sheet on which the image has been formed by comparing the scanned image with a reference image; and
a recording unit that records information identifying the discharged sheet and information identifying the inspected sheet in the memory, and
the printing apparatus comprising:
at least one processor; and
at least one memory,
wherein when a program stored in the at least one memory is executed by the at least one processor, the program causes the at least one processor to function as:
a printing unit that forms an image on a sheet transported along the conveying path;
a sheet discharging unit that discharges the inspected sheet from the conveying path; and
a notification unit that notifies the inspection apparatus of information identifying the discharged sheet,
wherein the inspection apparatus determines a page for which the inspection is resumed using the information identifying the inspected sheet and the information identifying the discharged sheet recorded by the recording unit in a case where a jam occurred in the conveying path of the sheet and printing is resumed.
