You will need the following
First install the printers on the server and share them accross the network.
All you need to do to install the printer is type in the RUN dialog box '\\Servername\PrinterShareName'
This will install it on that users machine with little input from the user. It simply opens up the printer queue screen.
Another method is to create a logon script.
Open notepad and enter the following, replacing servername with your server and printername with the printer share name.
Dim net
Set net = CreateObject("WScript.Network")
net.AddWindowsPrinterConnection "\\ServerName\PrinterName"
Now save this file with the extension '.vbs' and select any file instead of txt.
When you run this script it will install the printer without the user knowing.
