Using a combination of Group Policy and logon scripts, you can easily assign different default printers to different users.
At the college, where I work, we use mandatory profiles for students, who log into Windows XP machines in three different computer labs in a Windows 2000 Active Directory environment. Each lab has its own networked printer, which should be used by students working in that lab. But the profile can have only one default printer set, which obviously wouldn't work, since students in two labs would default to a printer that wasn't in their room.
Here is the quick and dirty VBScript that solves the problem:
set net = CreateObject("WScript.Network") workstation=net.computername location=left(workstation,2) printername="" select case location case "L1" printername="L1 LaserJet" case "L2" printername="L2 LaserJet" case "L3" printername="L3 LaserJet" End Select if printername<>"" then net.SetDefaultPrinter(printername) set net = Nothing
The script looks at the first two characters of the computer name (this specifies which lab the computer is located in) and then sets the default printer accordingly. If the student is logging on to a computer that's not in one of the labs, the default printer isn't changed. If you name printers differently in your own environment, you might have to customize the script further as needed.
We run this script in our own environment by specifying it as a logon script using Group Policy (so legacy Windows 98 machines ignore it), because all our labs have Windows XP anyway. All our machines also have the necessary drivers installed and configured, and the printers have the same names, so we just have to change the default printer.
