1. A printing system comprising:
a printing unit configured to perform print processing based on image data designated in a print job;
an inspection unit configured to perform an inspection of whether a printed sheet for which the print processing has been performed corresponds to a reference image for the inspection;
a discharge unit configured to discharge the printed sheet, which corresponds to the reference image for the inspection, to a first discharge destination and discharge the printed sheet, which does not correspond to the reference image for the inspection, to a second discharge destination;
one or more memories that store instructions; and
one or more processors that execute the instructions to:
cause the inspection unit to inspect a subsequent printed sheet, which is conveyed from the printing unit, subsequent to the printed sheet, which does not correspond to the reference image for the inspection;
cause the discharge unit to discharge the subsequent printed sheet inspected by the inspection unit to the second discharge destination even in a case where an inspection result of the subsequent printed sheet indicates that the subsequent printed sheet corresponds to the reference image for the inspection;
instruct the printing unit to abort the print processing relating to the print job in a case where it is detected that the inspected printed sheet does not correspond to the reference image for the inspection; and
determine whether to resume or cancel the aborted print job in accordance with a predetermined condition relating to the inspection.
