Suddenly the Printer Cannot Print over a Network Connection

When you have changed the network environment, such as the wireless router or provider, try making network settings for the printer again.

Connect the computer or smart device to the same SSID as the printer.

Turn off the devices you want to connect to the network. Wait for about 10 seconds, and then turn on the devices in the following order; wireless router, computer or smart device, and then printer. Move the printer and computer or smart device closer to the wireless router to help with radio wave communication, and then try to make network settings again.

Press the button to print the network connection report. If the report shows that the network connection failed, check the network connection report and then follow the printed solutions.

Try accessing any website from your computer to make sure that your computer's network settings are correct. If you cannot access any website, there is a problem on the computer.

Check the network connection of the computer. See the documentation provided with the computer for details.
