Terminal server printing from Vista client

We have several remote users running XP accessing terminal server (2003). We
recently added our first Vista client, but when connected, none of the local
printers appear. The printer is connected via USB and all local resources
are enabled. The XP clients required a FilterQueueType"=dword:ffffffff
registry entry but this has not made a difference to the Vista client.

The printer works fine locally and I was even able to manually add the
printer from an administrator TS session and print a test page from my own
machine, but the queue refuses to appear on the users machine.

Any help much appreciated!
