just got a officejet 6962 and am trying to clear the screen because I am not using it as a network printer it is just set up as a usb printer The screen on the front keeps Pictures and whatever it wants to on the screen. Is there any way since it is plugged into my computer with a usb plug just to have it say done or cleared instead of a question mark an copy document or another picture? Or is it not necessary? why is there a ? question mark there as well?
