4.  LIMITATIONS AND COMPATIBILITY OF THE RELEASE

    a.  The QR code icon, which opens the larger QR code, can also be scanned
        with a mobile device. However, if a hostname is used as the QR value
        and the hostname is changed, the printer must be restarted for the
        change to take effect. The large QR code will work correctly without the
        restart.
