Need sticky printer for multiple users

I have tried using PrintUIEntry batch files to retain default printer settings no matter who logs on (70 PCs and 800 students!). This worked some of the time. I tried installing the printer on LPT1 and redirecting to \\server\printer. That workedintermittently. I even tried copying a user profile (with printer installed) to Default User to retain the installed printer, this doesn't work for me, either. Why is Microsoft torturing us with this BS?! Anyone out there having better luck? Please respond. Thanks, Pete
