To improve convenience of print job management which is performed by a print server.

A print system is constituted by connecting an external print server 100, a printer 200 and client PC1-PC4 through a network. Also after sending out a print job to the printer 200, the print server 100 retains the print job and synchronizes the status of the print job with that of the printer 200 in accordance with notification from the printer 200. When an error is occurred at printing, the print server 100 shifts the print job corresponding to the error to a held state. Thereby a user can restart printing by effectively utilizing the print job stored in the print server 100 without reissuing the print job after inspecting a cause of the error.
