@Bcbeetle5, Welcome to HP Support Community!

Check for iOS updates and also, Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates. Refer to the document HP Printers - Updating or Upgrading Printer Firmware

If the issue persists, try using AirPrint to print photos. Refer to the document HP Printers - Printing from an iPhone, iPad, or iPod Touch for help.

Keep me posted.
