From Apple iOS, you can print from most
applications to a wireless HP printer. First, make sure your printer is powered on
and connected to a wireless network. On your Apple iOS device, open Wi-Fi settings
and make sure you are connected to the same wireless network
as the printer. Open the document, photo, email, or web page
you want to print, and then tap the Share icon. Tap Print or the Print icon. Tap Select Printer and select your printer. Change any desired print settings, and then tap Print. The item prints according to your settings.
