can't print from phone

[Avey2]

When prompting "Print" from I phone, Printer starts but prints blank page. This is new. It has worked properly for years.

@Avey2 Welcome to HP community,
I understand you need help with printing from the phone on your iOS device, here's a few steps that should help:

Set up the printer network connection

Make sure the printer and your Apple device are connected to the same wireless network.

On your Apple device, make sure Wi-Fi is turned on and there is a check mark next to the name of your local Wi-Fi network. If you are connected to a different network, tap the name of your network to join it.

Restart the printer, and then check the printer network connection status.

Printers with a touchscreen control panel: Touch the Wireless icon or open the Network Settings or Setup menu to view the network connection status.

Printers without a touchscreen control panel: Make sure the light next to the wireless icon or button is on and not blinking.

Place the printer within range of the Wi-Fi router signal, and then use the Wireless Setup Wizard or Wi-Fi Protected Setup (WPS) to the connect printer to the internet.

Let me know how it goes, we'll be right here and happy to help!
