Connecting my printer

Hi,

Any information about the exact printer model?

An AirPrint-enabled printer can print from an iPhone, provided that the printer and the iPhone are connected to the same network (Wi-Fi router).

Use AirPrint to print from your iPhone or iPad - Apple Support

If you are using AirPrint, but there is a problem with device discovery, you could try the following power-cycle sequence (with these waiting times; do not forget the router): Power off the Wi-Fi router, the printer, the iPhone, and all other connected 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.
