To perform print processing of a plurality of print jobs by only one-time authentication in a print server even when the plurality of print jobs are stored, and to prevent an interrupt of another print job when processing the plurality of print jobs.

A client terminal generating the print job and performing a print instruction has: a status discrimination means for discriminating status information of a print spool area; an individual authentication means; a print job information acquisition means for acquiring print job identification information of the print spool area; and a status control means for controlling the status information. By acquiring the print job identification information of the print spool area, the print job performed with the print processing by the one-time authentication can be restricted to the print job stored in the print spool area at a time point of authentication completion.
