how force printers drivers download on XP clients ?

i have Win2000 print server and XP client.

XP clients have built-in printers drivers installed but i
want to force them to download manufacturers print
drivers shared by windows 2000 print server.

Manufacturers print drivers shared by windows 2000 print
server are not all in version 3 (User mode ).

I try to change datedriver and version driver registry
key but no changes.

Can you give me a way to force download even if the xp
client print driver is newer than the server one ???
