Abstract
There is provided a device associative management system which is preferable for reducing cost and time and improving reliability. A network printer 200 can be set to a server printer 200 or a client printer 200. When the network printer 200 itself is the client printer 200, the network printer 200 sends status information in a status information registration table 560 to the server printer 200. In the case in which the network printer 200 itself is the server printer 200, when the status information is received, the network printer stores or registers the received status information in a status information registration table.
