I have never let anyone print me nor will I allow it willfully. You can refuse it, you can refuse a lot of things that the government, in its many forms, tries to force you into doing so that they can track and follow you and get into your business. But my main point on this is that if the school wanted to benefit from my willingness to volunteer my time then they would just have to accept that I wasn't going to compromise my personal privacy to do so. If they insisted then they'd just have to forgo my help and time.
