When a spool file processing program starts with a system permission, first, a impersonation to a user permission is performed, and then the spool file is divided into EMF for each page. After division, the permission impersonation is released. Subsequently, a new spool file can be created with the system permission based on processing information, such as a collate copy, a reverse order, or the like. In addition, when a new printing job after processing is generated or when a new EMF drawing process after processing is performed, the permission impersonation is performed in advance. Accordingly, when the new printing job after processing is transmitted to an external server PC, permission is performed with the user permission.
