i have a windows 7 laptop. i have a canon mg5250 printer. suddenly when i go to print a document, it says printer not responding?. I have put the wi-fi code in again and that has connected. printer settings are fine. rebooted the printer and yet i still get the same message
Un install the printer and drivers and start again. make a note of the ip address of the printer as it sets up.
If stops responding again it may be the computer is looking for the printer on the wrong ip address
If you have a copy of the printer settings from when you first set it up you could go to devices and printers and see what "port" the printer is connected to, it should match your printer settings but it is probably easier to start again.
