What is the Toggle Screen/Print button on the OfficeReady toolbar in PowerPoint?
Most presentations are designed to be shown in color, but handouts are usually printed in black and white. Shaded fills, filled objects, and backgrounds that look good on the screen make the printed handouts unreadable. The toggle button provides the functionality to view the slides in either the screen version or the print version. To view a slide in its print version or vice versa, click the Toggle Screen/Print button. This displays the print/screen version of the slide.
