Vista - Remote Printing and Vista - HELP!!!!

Host O/S: Vista Home Premium
Terminal Services O/S: Windows Server 2003 (32-Bit)
Printer Driver(s): LaserJet 3050 PCL 5e
Universal Printer Driver 4.1 (PCL5)

The LaserJet 3050 is connected to the Vista laptop (Compaq) via USB. The
printer has printer pooling enabled and ports LPT1 and DOT4_001 are checked.

The UPD 4.1 driver has printer pooling enabled and ports LPT1 and DOT4_001
are checked.

This very configuration has been flawless for XP Pro SP2 machines connecting
with OfficeJet 7100 and LaserJet 3015 printers.

However, I cannot get the Terminal Services session to communicate with
Vista to recognize EITHER the 3050 driver or the UPD driver!

I have contacted HP Printer and Compaq Laptop support. No one has a clue
what I am talking about. I have read the HP Printers supported in Citrix
Presentation Server environments white papers and see that the LaserJet 3050
is included on the compatible printers list.

I also see that the 3050 is a supported printer on the upd driver site. It
also shows that driver is compatible with Vista/2003/Terminal Services.

HELP!!!
