Power Users can't set default printer

Does anyone know a workaround for this problem. I am using con2prt.exe from the NT resource kit to map printers to specific computers but only users with local Admin rights get a default printer. The printers are installed but none are set as a default. i.e: in Word if you select print the default is blank, it will give you a list to select from, but in some software this will not work. I can't give all users Admin rights...I have tried give load drivers rights, and full manage rights on the printer's security.

I've never done it, but found this article interesting:

There are a few other articles in the KB...
