Nemůže být problém v tomto?

NOTE: The HP LaserJet P1500 Series network models only support IPv6.

My HP LaserJet P1505n, connected by Ethertnet to my LAN, has been working flawlessly for three years. The last time I turned it on, it could not get an IP address by DHCP. I verified this by printing a self test page. The IP adress is 0.0.0.0. I looked at the self test page from three years ago and saw that the IP address was 192.168.0.100.
