Unable to print photos from my iPhone

Thank you for the information.

This is an AirPrint-enabled printer (About AirPrint - Apple Support).

With AirPrint, you can print from an iPhone, connected to the same network (Wi-Fi router) as the printer, without using an app from the printer manufacturer.

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

Is this the way you have printed from the iPhone, or are you using the HP Smart app?

Would it be correct to assume that you can print photos from the laptop as well?

Any change if you try to print a photo (via the printer's control panel) from a memory card?

Hi,

Any information about the exact printer model?

Also, by "any other source", do you mean from another app on the iPhone, or from another phone or computer?
