A host device includes one or more menu groups provided in a driver program to drive an external device connectable to the host device and to set driving options of the external device, a user interface section connected to the one or more menu groups to provide a user interface screen to independently display the one or more menu groups separately with respect to each other, and a display section to display the user interface screen provided by the user interface section. Accordingly, a user can conveniently set the driving options of the external device connectable to the host device after the driver program is installed in the host device without inconvenience caused by moving between menu groups.
