With the Windows NT, 2000 and XP network printer architecture, the client
computer does not get a complete printer object as it does for a local
printer or as is done on Windows 9x clients.
When you examine the Properties of a network printer from the Windows XP
computer, you are actually examining the Properties of the printer on the
print server. Although there is a printer driver installed on the client
(Windows XP) computer, that is not what you see in the Printer's Properties.
If the user account logged on at the Windows XP client has the appropriate
rights and permissions on the print server, that user account can modify the
Properties of the printer, including the driver, on the server.
To see and manipulate the printer drivers on the client computer:
1. Open the Printers and Faxes folder on the client computer
2. click File, Server Properties
3. select the Drivers tab
What you see there are the drivers on the client computer; you can delete or
update the drivers on the client from there.
In many cases, to change the printer driver on the clients, it is more
effective to change the printer driver (or the Additional Driver if the
client OS is different from the print server OS) on the print server. Then,
the clients should automatically get the updated driver from the server.
