default printers with mand. profiles

Hi!
I’m NetAdmin in a School. I’ve 120 workstations(NT4.0, Sp6)running with a NT4.0 Serverfarm (Sp6). The computers are located in 5 different rooms, one printer for each room (some Lexmark Optra, some HP LaserJet). There are approx. 400 users using one mandatory Profile. At the moment I have one default printer defined in the profile. But users often forget to change the printer if they are in another room. My Question is: Is there a possibility to give each user the Printer for the room he is in?
Thanks,
Markus
