how to print from my iphone 13 pro max?

Hi,

As Tesserax indicated, you would normally need an AirPrint-enabled printer in order to print from an iPhone.

If you do not have an AirPrint printer, there may be a workaround (via an app from the printer manufacturer, or by using a Mac with special software as a print server). In this case, please post back with the exact printer make and model.

Your home printer must support AirPrint. If so, then you can use this feature to print from your iPhone.
