Why isn't Easy Print working?

I know there have been many posts about printing on TS 2008.  Here's another.

I have four Terminal Servers, all with identical printer drivers, version, etc. installed (64 and 32 bit driver installed on all servers)

Here are the problems:
1.  Even when user has correct driver (name and version match), the user cannot see *any* printers within our applications.  Great Plains does not support Easy Print, so I know the drivers have to match, which they do.  Yet the system log on the server complains:  "the attempt for IT-7345 (redirected 4) to use a Windows NT 4.0 (kernal mode) driver failed because this version of Windows does not support Windows NT 4.0 printer drivers...." 

2.  I don't understand why Easy Print isn't kicking in for applications such as Word 2007, which are supposed to support Easy Print.  I see the same error as above.

So users can't print at all, can't even see printers, even with exact driver matches.  Easy print no-worky either.  I have a GPO on the Terminal Server OU to force use of Easy Print when possible, too.

Help!!!
