Adding a printer automatically

I need to find a way to add a new printer to the user's system automatically when they install my program. I am able to do this in Windows XP/2k by using the shell command:

rundll32 printui.dll,PrintUIEntry /if /b "VirtualPrinter" /f ".\lj456p5.inf" /q /r "FILE:" /m "HP Laserjet 5" /z /u

I also need to be able to do this in 95/98/Me/NT, but this command is not suppored in these OSs. Does anyone know of another program or script that can be used to accomplish this same task? Thanks!
