Local USB printing over RDP

Most USB printers work with a remote session. I understand that this is not officially supported by Microsoft until 2008 server. I also understand that RDP v6.0 provides more support.

I am unable to get a Dell 720 to print through a remote session. The printer is recognized and the print job enters the queue with status of printing yet does not print.

What would be a comparable workaround? Possibly connecting the printer to a print server and mapping the printer locally and to the TS?

Any suggestions appreciated.
