A line concentrator classifies printers connected via a communications network into groups according to the capabilities of the printers and includes a storage section which stores a VLAN table classifying the printers into groups and listing virtual addresses corresponding to the respective groups. When a monitoring section receives data addressed to a virtual address, it refers to the VLAN table and performs controls so as to transmit the received data to all of the printers belonging to the group corresponding to the virtual address. Thus, it is possible to eliminate the problem, such as concentration of jobs to a specific information processing device, and to provide a line concentrator capable of rapidly performing data transfer processing.

A display device of an electronic apparatus according to the present invention is a display device of an electronic apparatus for setting a plurality of conditions for a process of the electronic apparatus through an input portionwhile displaying the conditions before the electronic apparatus performs the process in accordance with the conditions. The device comprises a determination portionof determining whether or not each of the conditions has not yet been set, and a liquid crystal display panelof displaying notifying information indicating to what degree conditions remain to be set. The liquid crystal display paneldisplays buttons for setting the respective conditions on a screen thereof, and displays button(s) which have already been pressed as being unfilled and the number of buttons which have not yet been pressed. Therefore, by viewing the screen, the number and types of conditions which have not yet set can be known.

There is provided a mediation section () for switching between an active status in which data transmitted to a specific address is registered and processed and a non-active status other than the active status. When the mediation section () judges that unprocessed data stored in a data storage section () cannot be processed in a predetermined time, the mediation section () instructs one or more other MFPs to change into the active status and causes the MFP including the mediation section () to change into the non-active status, so as to cause a data processing section () to process the unprocessed data. As a result, it is possible to perform mediation concerning a job (data) without using a server.
