If you wish to include useful information that should only be visible to you (the speaker) during your next PowerPoint presentation, here's how to do that.

Notes Pages prints one slide per page, with Speaker Notes below it. So, to print your slides with Speaker Notes, click Print. Other options under Print Layout include Handouts, print-only slides ...

Speaker notes are on a per-slide basis. Unlike headers and footers, which appear on every slide and are visible to the audience, notes appear only on the slides you add them onto.
