When it is determined by the post-process determination unit that a received top job requires a bookbinding process (post-process) and that a received subsequent job does not require a bookbinding process (post-process), the sheet setting determination unit determines whether or not there is a match between the sheet size (sheet setting) of the top job and the sheet size (sheet setting) of the subsequent job, and when it is determined by the sheet setting determination unit that there is a match between the sheet size (sheet setting) of the top job and the sheet size (sheet setting) of the subsequent job, the execution management unit causes the printing machine to perform the printing process on the basis of the subsequent job during the warm-up of the bookbinding device.
