Maven - I'd just let her get you the printer. I understand entirely about parents not taking their adult children's word for anything - when I go home to visit my parents, they do not even let me borrow a car (they have 2) to run an errand. Now, when they come to visit me, I give them my car and trade off with my roommate. My step-mom always just tells me my dad can drive me where ever I want to go. Nor do they listen to me about anything - A friend told me that even though I am a successful adult (for 3 decades now) they still treat me exactly like a kid. It used to bug me to no end and I have finally gotten to the point of realizing that is just they way they need to be and let it go (most of the time.) Take care and try and realize that it is just your mom's dance and that it is not really about you!
