Are you connected wirelessly? (via your router) If it will scan from the controls on the printer but is doing nothing when you try to print using any method from a pc or laptop then you have connectivity issues. Check in settings ( printer) whether it is still connected or try switching it off, waiting , then switching it back on. If you are wireless and have wps facility on your router, press the wps button on the hub and within 30 seconds, the wps button on the printer. They should then "find" each other.
