A host that controls jobs of a printer obtains client identifying information within a job control request, which is received from a terminal, while obtaining the job information and client identifying information of the print request from the printer, and storing the same in a job information storage unit. For each job included in the job information that is obtained from the printer, a job control capability determiner compares the client identifying information (of print requester) and client identifying information of the terminal that made a control request. When both of the client identifying information is identical, it is determined that the control is allowed. When it is not identical, it is determined that the control is not allowed.
