Unable to add HP LJ P3005dn network printer to Vista Ent.

We run a Windows Server 2003 R2 domain with 400+ Toshiba TECRA M7 notebooks.
All the machines are running Vista Enterprise Edition.

Attached to a TCP/IP port on the Server 2003 is a HP Laserjet P3005dn
network printers with print driver for Vista, which is shared and has the
latest drivers. All the users have logon script to connect to the network
printers thru Win2003 R2 Print server automatically.

Here's the problem: When I try to run the logon script manually on the Vista
machine, I get an error message stating that it needs a printer driver for
Vista.

How can I automatically install the network printer thru the print server
without asking the user to install the print driver for Vista?

Note: For XP clients, the logon script works without a problem. It will
automatically connect to the network printers thru the print server.




Thank you all in advance for any assistance.
