Print from your iPhone, iPad, or iPod touch

Use AirPrint on your iOS device:

1. When in an app that you'd like to print from, tapor. Depending on the app, the icons might be in different places. If you need help, check the user guide or help for that app.
2. Tapor Print.
3. Choose your printer and the number of copies you want, then tap Print.
   • To look for available printers, Wi-Fi must be on for your device. Go to Settings > Wi-Fi to see if it's on.
   • If you don't see your printer, make sure that you're within range.

You can view or cancel printing in the Print Summary. To see the Print Summary, double-click the Home button and swipe left. The Print Summary is available only when printing.
