[ The user client 200 can perform the Bluetooth search again using the name field printer2 of the printer 101. [ Even if the Bluetooth search name of the printer 101 is changed, the name field of the Bluetooth search name of the printer 101 is not changed. Thus, the user client 200 can find the printer 101. [

The user client 200 can perform the pairing again with the printer 101 having the changed Bluetooth search name. Therefore, in the printer list displayed on the user client 200, printer2_Y may be deleted and printer2_R may be added.

In one embodiment, all of the printers in which the pairing information is stored may be displayed in the printer list. In addition, only the currently paired printer can be displayed in the printer list.

When only the printer currently paired with the printer list is displayed, if the pairing with the printer 101 is canceled, the printer2_Y will be deleted from the list. Also, when re-pairing with the printer 101, printer_R can be added to the list.

If all the printers in which the pairing information is stored in the printer list are displayed, even if the pairing with the printer 101 is canceled, the printer2_Y will not be deleted from the list. In this case, if the pairing is canceled, the Bluetooth search name of the printer whose pairing has been canceled can be set to be deleted. However, in this case, there is a disadvantage that the pairing information must be retrieved and stored again upon reconnection.

Accordingly, the user client 200 does not delete the Bluetooth search name from the printer list and only has the same name field at a later time. However, if a printer name having another color field is added, the user client 200 does not delete the Bluetooth search name As shown in FIG.

For example, when the printer2_R is searched and added to the printer list, it is possible to prevent the confusion of the user by deleting the printer2_Y.
