A printing apparatus includes an input unit, a specifying unit, a storing unit, a printing unit, a receiving unit, and a control unit. The specifying unit specifies a number of sheets for printing image data pieces of a plurality of pages. The receiving unit receives a binding process execution instruction. When the sheets are printed in the reverse order and the printed sheets are bound, the printing unit had started the reverse order printing after all the image data pieces were stored. When (i) the sheets are to be printed in the reverse order and the binding process is set to be executed and (ii) it is determined, while the storing unit is storing the image data pieces, that the specified number of sheets exceeds the number of sheets that can be bound, the printing unit starts printing in the page order before all the image data pieces are stored.
