How to Print the Screen on an iPad
Capturing a screenshot on an iPad is just a matter of pressing the Sleep/Wake and Home buttons at the same time. Once the screen is captured, you can print it directly to any nearby AirPrint printer on your wireless network from the iOS 8 Photos app. If you don't happen to have an AirPrint printer, there are several ways to send the screenshot to your computer to print it from there.
Press the "Home" button and "Sleep/Wake" button at the same time. The screen flashes briefly and the iPad makes the sound of a camera shutter indicating that the screenshot has been captured.
Launch the "Photos" app. By default, the Photos app shows photos by date. The screenshot you just took is displayed as the last thumbnail on the screen. If you've been navigating around the Photos app, tap the "Albums" icon at the bottom, select "Camera Roll" and scroll to the bottom. Your screenshot is the last photo thumbnail. Tap the "Select" button.
Select the screenshot you want to print. A blue arrow appears on the thumbnail. Tap the "Action" button in the upper-right corner of the screen.
Click the "Print" icon if you have an AirPlay printer on the same network as your iPad. This opens the Printer Options window.
Tap "Select Printer" and choose your AirPlay printer. Specify the number of copies you want printed and any additional available options, such as collated printing, depending on the printer model.
Sending a Screenshot to a Computer for Printing
Send a file to a nearby Mac computer using AirDrop. After selecting the screenshot and clicking the "Action Button," enable AirDrop by swiping up from the bottom of the screen and selecting "AirDrop" in the Control Center.
Select the Mac computer from the AirDrop section of the screen. Mac computers must have Bluetooth enabled to connect with AirPlay, and the user must accept the incoming file transfer.
Select "Mail" to send the screenshot to a computer's email account as an email attachment. You can also share the screenshot using social media, like Facebook or Twitter, and then access the photo from the computer's Web browser.
Send the file via a cloud-based utility: open any cloud-based, file-sharing app you already use regularly, such as Google Drive, Dropbox or OneDrive. Upload the photo to your cloud account and download it from your computer.
