How to prevent the status bar from appearing in an iPad screenshot?
Unfortunately, there is not a way to remove the status bar unless you are in an app which is full-screen and chooses to hide that information. However, you can crop the image in the Photos app:


Take Screenshot
Open Photos app
Open screenshot
Press Edit in upper-right of screen
Depending on rotation of screen, look for the Crop symbol
Press Crop and drag the white boxed frame to match the image you'd like
Press Done to finish cropping


Here is a Wikihow on how to do it, with screenshots.
