A printing apparatus that is connected to a post-processing apparatus, to which the printing apparatus passes a printed sheet which has an image printed thereon, wherein the post-processing apparatus is configured to discharge printed sheets, each of which has an image printed thereon, to a first discharge unit without the printed sheets reversed nor subjected to execution of saddle-stitch bookbinding process, and discharge the printed sheets to a second discharge unit with the printed sheets reversed and subjected to the execution of the saddle-stitch bookbinding process,
- the printing apparatus comprising:
- a reception unit configured to receive setting for executing the saddle-stitch bookbinding process;
- a determination unit configured to determine whether or not the number of sheets used for a print of one copy exceeds a executable number of sheets which can be subjected to the saddle-stitch bookbinding process;
- a control unit configured to, in a case where the reception unit receives the setting for executing the saddle-stitch bookbinding process, control the printing apparatus to pass the printed sheets to the post-processing apparatus in a first order when the determination unit determines that the number of the sheets used for the print of the one copy exceeds the executable number of sheets, and control the printing apparatus to pass the printed sheets to the post-processing apparatus in a second order, which is reverse to the first order, when the determination unit determines that the number of the sheets used for the print of the one copy does not exceed the executable number of sheets.
