1. A peripheral device shared by a plurality of user terminals, the peripheral device comprising:
a volatile memory;
a display device;
a non-volatile memory; and
a processor coupled to the volatile memory and the non-volatile memory, the processor configured to:
store, into the non-volatile memory, a connection history of a user terminal to the peripheral device;
when a first mode or a second mode is active, store, into the non-volatile memory, settings information specifying an operation of the peripheral device in association with identification information of the user terminal, the first mode being an operation mode in which only the settings information of a selected specific user is displayed, and the second mode being an operation mode in which all settings information registered in the peripheral device are displayed;
when a third mode is active, store, into the volatile memory, the settings information in association with the identification information of the user terminal, the third mode being an operation mode in which only the settings information of a user connected to the peripheral device is displayed;
select the identification information of the user terminal stored in the non-volatile memory, based on the connection history stored in the non-volatile memory;
display, on the display device, the selected identification information of the user terminal or the settings information associated with the selected identification information of the user terminal without displaying information relating to another user terminal; and
when the third mode is active and a state in which the peripheral device is exclusively used is cancelled, delete the settings information from the volatile memory.
