Thanks to everyone for wanting to help. As it turns out, what my professor meant was, "I have converted this PowerPoint to a PDF file and disabled printing on it, and then I had the audacity to tell an entire class of 250 people that no one would ever be able to print this file, so I expect everyone to rewrite the notes."
I don't mind encouraging people to rewrite notes, in fact, its good for memory retention. However, she made a critical error in assuming that because we're all pre-med students, we don't know dick about computers. On top of all this, I'm prior military and worked with Special Operations Command Pacific (SOCPAC) for 4 out of my 5 years. Telling people like myself and ones I worked with that we "would never be able to" do something is going to make us march through Hell and back to find a way to make it happen.
Since it was just a PDF, I stripped out the password, printed it off, and handed it to her the next class period with a warning, "Any digital product of any kind and probably will be eventually hacked or circumvented. My suggestion is that you never tell someone what they can't do, and next semester, just omit the fact they file can't be printed. The kids will figure it out on their own." And at which point I promised her I wouldn't distribute the unlocked file, and that I did this merely out of principle and to prove a point.
So in short, this was merely a matter of me being a dick in the face of authority, so thanks for wanting to help guys.

(by the way I'm sincere about that, the AnandTech community has always been one of the best on the net when it comes to lending a helping hand)
