Changing Page Setup Options
Before you print a presentation, you can use the Page Setup dialog box to set the proportions of your presentation slides—standard and wide screen (New!)—and their orientation on the page. You can also control slide numbering in the Number Slides From box. For a new presentation, PowerPoint opens with default slide page settings: on-screen slide show, landscape orientation, and slides starting at number one. Notes, handouts, and outlines are printed in portrait orientation.
