PRINT SYSTEM, PRINTING APPARATUS AND INFORMATION PROCESSING APPARATUS, METHODS OF CONTROLLING THOSE, AND STORAGE MEDIUM

A print system comprising a printing apparatus, an information processing apparatus operable to input a job to the printing apparatus and thereby cause the printing apparatus to print and an inspection apparatus operable to receive sheets printed and discharged by the printing apparatus and inspect the sheets. The inspection apparatus compares the respective received sheets and a corresponding reference image among reference images registered in a predetermined order, and thereby inspects images of the respective sheets. The printing apparatus skips printing of a blank page in a case that a blank paper saving function is designated, and in a case of an inspection mode, performs a warning if the blank paper saving function is designated.
