Question

I have recently hoocked back up my MFC 9200C to my computer and it does not communicate. I remember having this problem before and someone showed me how to reset the printer on the pad on the printer itself, but I don't remember. Any solutions?My printer is hooked to the computer by a USB cable.When I give a print command nothing happens.
