Solution when the Wi-Fi printer cannot print First check the communication environment
If you have trouble printing with a Wi-Fi connected printer, check the signal strength.
Printing is not executed on the printer connected via Wi-Fi. There are various causes for such troubles, but there are also cases where there is a problem on the network. The usual way to check the operation of Wi-Fi connected network devices is to execute the "ping" command at the command prompt. [Visual explanation] Wi-Fi printer, solution for printing failure
■ First, find out the IP address of the device
First, let's find out the IP address of the network device. There are several ways to find out, but it's easy to use the smartphone app "Fing". Once you know the IP address, use the ping command to check the response of the device. If "Timeout" or "Unreachable" is displayed, communication is not correct. Reconnect your printer to your Wi-Fi router or restart your printer. If there are no errors, the communication itself is successful.
■ Restart your router and printer
In the case of a printer, printing may not be possible if the IP address is automatically changed by restarting the router. In that case, the theory is to restart from the router to the printer in order. Some printer manufacturers have tools that can help you solve problems, including networks.
