iPhone X not locating printer

Hi,

Would it be correct to assume that your printer is listed in About AirPrint - Apple Support as a supported AirPrint model? If so, in order to print, the iPhone and the printer must be connected to the same network (Wi-Fi router).

If all settings are OK, and If there are difficulties with AirPrint, you could try the following procedure:

Power off the Wi-Fi router, the printer, the iPhone, and all other devices/computers. Wait two to three minutes. Power on the router. Wait two to three minutes. Power on the printer. Wait a minute or two. Power on the iPhone. Finally, power on all other devices/computers.

If not an AirPrint printer, please post back with the exact model.
