A plurality of image processing apparatuses 1 and a remote access apparatus 2 which remotely operates each image processing apparatus 1 are connected through a network 3. Each image processing apparatuses 1 have a same operation screen. The remote access apparatus 2 accesses the plurality of image processing apparatuses 1, and acquires screen data for displaying an operation screen A, from one of the image processing apparatuses 1. The remote access apparatus 2 displays the same operation screen A as the operation screen of the image processing apparatus 1. When a user performs an operation for outputting reports on this operation screen A, the remote access apparatus 2 requests output from each image processing apparatus 1. Each image processing apparatus 1 creates a report and transmits it to the remote access apparatus 2. Therefore, it is possible to acquire reports about the conditions of the plurality of image processing apparatuses outputted from the plurality of image processing apparatuses by one operation.
