Image forming apparatus forming location free print system and print job retrieval method by the same are provided. An image forming apparatus forms a location free print system in which the groups of networks made up of a plurality of image forming apparatuses include a plurality of groups in which one image forming apparatus functions as a main server and an address list of addresses of main servers of all groups is shared by the main server of each group. A job list of print jobs of the image forming apparatuses is shared by each image forming apparatus in the first group. If a user is authenticated, then the image forming apparatus retrieves print jobs of the user registered in the first group from the job list. If retrieving print jobs of the user registered in a second group, the image forming apparatus instructs, via a main server of the first group, a main server of the second group to retrieve print jobs of the user.
