Q: Ipad Not connecting to wireless printer hp 8500?

You may have to troubleshoot the printer. You could try rebooting the iPad first.

Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

If it still can't find the printer, turn the printer off and on again. Still no luck, look for a firmware update fro the printer on the HP support site. You can also try power cycling your router by unplugging from power for about 30 seconds and then plug it in again
