I have a problem setting up my HP LaserJet 4000 N with an Ethernet cable attached and plugged into a LAN port of my apple TC.

I can't configure it. (USB does it work, but that was my neighbour's cable)

I tried to look up the ip, mac adress etc to set a DHCP thing.

I won't come out without any help.

Some info:
I'm using a Netopia Cayman and my apple time capsule.
Both NAT so i can connect as much as PC's and Mac's i can.
