Solution
When attempting to print using a wireless connection, you may see a "Printer not responding" message.
Review the possible causes, then visit the linked article to resolve the issue.
-
The computer and router have lost connection. Restart the computer and try to print again.
-
The printer is too far from the router, resulting in a low signal strength. Move the printer closer to the router.
You can print out the network settings and check the listing for signal strength. The higher the percentage, the stronger the signal.
-
The router and printer can't communicate. Power the router and printer off then on to restore communication.
-
A firewall on your computer may be blocking the ports that communicate with the printer. Configure the firewall to allow network communication with the ports.
Refer to the documentation for your firewall to learn how to configure it.
-
Make sure your printer and computer are connected to the same network.
