Hi Guys, My GF has a Lexmark X6170 printer which she uses with her PC. I have tried to hook up the usb from the printer to my MB and tried to print, However it always gives me a message " printer not responding. I don't know what am I doing wrong. As far as I remember, I don't need to install the cd that comes with the printer that my GF installed on her PC, or do I have to install the CD that came with the printer on my MB. Any recommendation would be appreciated. Cheers!!!
