In accordance with the embodiment of the present invention, even if the print file stored in a detachable memory or the storage area of a mobile terminal is a file created by application software which cannot be handled by a print processing apparatus, the print file can automatically be transferred to a print processing server in which the print file can be converted into print data and returned to the print processing apparatus, as long as there is such a print processing server which is connected to a network NW and supports the application software, and thereby it is possible to directly print the print file so that the user need not run the process of converting the print file into the print data by himself. In addition, since the print processing apparatus centrally manages the local information of a plurality of servers connected to the network NW, it is possible to quickly perform jobs as viewed from the whole system.
