Need Help in Raising Domain From Mixed to Windows 2003

Here is my scenario:
My Network is comprised of 2 domains, WindowsNT4 and Windows 2003. We have been migrating everything off the old domain to the new one. There are no users authenticating to it and the only machine left is a print server which happens to be a domain controller. All other computer have been migrated to the Windows 2003 active directory. I am running in mixed mode and want to raise the domain. The problem is that I cannot get rid of the old NT machine right now. There is a printer on there that is mission critical. It is an old one and does not operate well on the updated 2000/2003 printer driver.
I thought I could just make this old machine a member of the newer 2003 domain but since this is the last machine in the old domain, I cannot seem to demote it to a member server.
Can I go ahead and upgrade the 2003 domain from mixed to native since I do not have any users authenticating the NT machine. I presently have a trust between the domains. If I can do that can you point me in the right direction of how to do it. I have already migrated the old Exchange 5.5 and our Exchange 2003 is running in native mode right now.
Any Help Will Be Useful !

You can raise the forest and domain level to W2k3 Functional Level without it influencing the trust. The domain level only is only important for down-level *DCs* in the same domain, you can have a trust between a W2k3 in full functional level and an NT4 domain.
Another option might be to use the third-part tool "UPromote" to demote your current NT4 DC (a "native" demotion is not possible in NT4) to a member server, and then join it to the AD domain. Make sure you have a working backup of that machine before you demote it, beause permissions will have to be changed.

Great idea .. I will look at UPromote first ..
I figured I would be OK in promoting to W23 functional since no one is authtenticating on the old server, but I just wanted to get the opinion of an expert since I have never done this before ... My goal would to get rid of the old domain if I could ... but I do want to have the functions of a native 2003 domain

It wasn't in my budget to pay $130. to demote the old NT Server, so I just raised the domain and things didn't crash and go boom .. so all is good ... Thanks
