Wi-Fi® LED is lit in blue (QL-810W) or WLAN icon appears on the LCD (QL-820NWB) but the printer cannot communicate with other devices via Wi-Fi.
First you must configure the wireless network settings of your printer to communicate with other devices via a wireless LAN.
After the printer is configured, computers on your network will have access to the printer.
To use the printer from these computers, you will need to install the drivers and software.
You can use the Communication settings in the Printer Setting Tool to easily configure network settings or check the status of multiple printers.
