It worked perfectly well up until yesterday. This morning it wouldn't print. I deleted printer and then tried to reinstall and it didn't come up with printer, although did this evening. However, having tried all sorts of things from the Brother website (it's a DCP-770cw) I still can't get it to print. It says on that "The Printer is not connected". Wifi on other devices is fine. No error message on printer screen so am a bit flummoxed. Any ideas please?
