How to connect a my iPhone to Epson l3150 printer?

There are two ways:

1. If the printer support AirPrint. see list => About AirPrint - Apple Support
2. The printer manufacturer has an app for the iPhone.

Work around, send as an email attachment to a computer and print from there.

Hi,

Unfortunately, the L3150 does not appear to support the AirPrint technology. This means that an app from the printer manufacturer would be needed after all (unless you want to invest in an AirPrint-enabled print server, or could print via a third-party app and an appropriate Mac). The L3150 is mentioned in https://support.epson.net/appinfo/iprint/en/ as supporting Epson iPrint (https://apps.apple.com/us/app/epson-iprint/id326876192).

Good luck!

If you have a Mac get the Printopia app for it.
