Refer to the printer manual, turn on the printer's wireless printing function and connect to the network, or use the printer's WLAN direct connection function (the printer will create a WiFi name, which generally includes the printer model);
3. Make sure that the printer and mobile phone are connected to the same network.
Please make sure that the printer and the mobile phone are connected to the same network (under the same router) before the mobile phone can search for and connect to the printer.

Note: If you can't find a printer through "Find a printer directly connected to WLAN", you can go to phone settings-WLAN to check whether the WiFi name created by the printer is displayed and connected in "Available Networks". If it is not displayed, please refer to the printer manual for setting. If the WiFi name is displayed but not connected, you can manually click the Connect WiFi name and then try to print the file;
