One of my printers (Pantum P2500W) in AirPrint defaults to A4 paper size and I can't figure out how to change it. Comes up the same on both my iPad Air and iPhone6. Under Advanced Settings the A4 Paper Size is ghosted so I can't select it for change. I'd like it to default to 8.5" x 11". I've called Pantum and they don't have any ideas. I'm using iOS 8.4 on both devices. Any ideas?

Have you tried going into a different setting? A4 is usually a UK or different location-specific setting. Try seeing if you can set your location to the USA in a different setting area.
I just went to Settings > General > Language & Region and changed to the United Kingdom and back to the US but it didn't change the AirPrint setting.
Here's the user manual online, maybe this will help: http://www.manualsdir.com/manuals/592838/pantum-p2500w-p2500-p2200.html
Here's how to reset everything back to factory defaults, maybe try this?
If you want to reset all parameter settings of the printer, you can restore to the factory settings
by long pressing "Cancel/Continue" button when the printer is powered off to power on it and
holding for 10 seconds until the printer enters Ready status to finish the resetting work.
