sel206, can I ask why your father "does not allow me to use computer or internet at home"?

Only you know what your situation and parents are really like, but I don't really think it's a matter of "my parents have the right to do whatever they want with their business and life". Did you buy the printer with your father's money? because if you didn't then it's your property, your business, and your life.

I understand that I know nothing about your parents, but what I'm trying to say is that parents can be wrong, and most certainly can do wrong. Your anger might be fully justified. After all, they're your parents; they're supposed to provide for you and support you.
