Q: When I select print on my iPad the loading preview disappears and I cannot see the document anymore

Hello Cswqueen,

Thank you for using Apple Support Communities. It's my understanding you've been unable to AirPrint with your iPad. I know printing from any device can be very helpful and sometimes crucial. I'm happy to help.

If you haven't already, try restarting the iPad. This can resolve many unexpected behaviors. Use the steps below.

1. Press and hold the Sleep/Wake button until the red slider appears.
2. Drag the slider to turn your device completely off.
3. After the device turns off, press and hold the Sleep/Wake button again until you see the Apple logo.

Restart your iPhone, iPad, or iPod touch

If the issue persists, make sure your iPad software is up to date.
Update the iOS Software on your iPhone, iPad, or iPod touch

Here's some additional information on AirPrinting.
