A print application (703) issues print job grouping start and end instructions to a print system (client) (707). The print system (client) (707) reads out the job information spooled at the time of reception of a grouping start instruction from a spooler (705) and stores the information. The print system (client) (707) reads out job information spooled at the time of reception of a grouping end instruction from the spooler (705). The print system (client) (707) then extracts jobs that do not coincide with the stored job information as print jobs to be grouped from the spooler (705) and outputs them.
