Question : How to hide redirected printers in Terminal Server

We have multiple companies logging onto one terminal server.  The IP based printers with the correct permissions can only be seen by the person or groups that have access.  The problem is that redirected local printers can be seen by everybody.  Is there a way to hide redirected printers based on the company that is logged in.

sorry i should have added.
Only administrators, domain printer administrators, and power users on the terminal server can see other users redirected printers

hopefully this will all change in Longhorn (server2007) as per http://blogs.msdn.com/ts/archive/2007/05/03/introducing-terminal-services-easy-print-part-2.aspx
