Printers not automapping on 2003 terminal server

Afternoon All,
I hope someone can help. It might be a quick answer.
We are running a 2003 SBS Server with published printers. The printers map fine when logging onto a XP Workstation. When logging onto our 2003 terminal server the printers do not map. You can map manually and printing works. I had a ton of the 1111 Event ID in system event viewer on the TS. So i have used the TS printer redirection tool to add the missing drivers. No longer get the 1111 errors but still no mapped printers at logon. I have done a ton of reading but i think the issue is down to SBS. Can somebody put me out of my misery : )
Thanks
Martin
