4. LIMITATIONS AND COMPATIBILITY OF THE RELEASE

    a. The QR code icon, which opens the large QR code, can also be scanned
       with a mobile device. However, if a host name is used as the QR value
       and the host name is changed, then restart the printer for the
       change to take effect. The large QR code works properly without a
       restart.
