Hi Gary and welcome to the Fine Tuned Mac Forums.....
I think you might have a couple of additional issues to resolve beyond the IP address, however, that looks like the first place to start for now.
Before we go there let's get some additional info:
What model Macintosh are you using?
What version of Mac OS are you running?
Is your Mac attached to a home network? If so, how....(wired ethernet or WiFi)
If on a home network, what IP address does your Mac have?
....and lastly, where did you find the documentation for your optional ethernet card installed in the printer? If it's the C12C824052 internal 10/100 base T card, then I've found it as well.
With the answers to the above questions we can move you forward to a solution or determine that you should maybe pick a different printer for your needs.
Let us know.
