I have a Dell 3130cn Color Laser Printer but it's not being recognized anymore on my HP laptop running Windows 7. I put in new toner but that is not the problem because it still won't work. I uninstalled the driver from Dell and reinstalled the same driver but printer still does not work. The printer does turn on and I don't see any error messages on the display, I also restored the defaults on the printer. Does anyone have any advice? Thanks.
