Just a bit of info that might help someone out.
I have just installed a new x64 2008 server and it is acting as a print server. It has taken me all weekend to get my head around the blooming thing needing the x86 ntprint.ini file. Well, here is a link which works and might help someon out:
NeopAdmin: x86 Print Drivers installed to Server 2008 x64 Server
That is all.
