What is needed to print the presentation using a layout of three slides per page?

To print a presentation with a layout of three slides per page, you would need to use the option that specifically allows you to control the number of slides printed on each page. Choosing the slides per page setting directly addresses your requirement by indicating how many slide images will be printed on a single page, thus allowing for a compact and organized printout.

When you want to print multiple slides on one page, this setting is essential, as it changes the layout format and saves paper while still allowing viewers to see the key points of each slide. This is particularly useful for sharing drafts or for presentations where viewers do not need to see full individual slides.

Other options do not provide the necessary functionality:

• The full-page slides button would print each slide on its own page rather than in a reduced layout.

• The page setup button generally involves layout dimensions and margins rather than the number of slides per page.

• The print layout button does not specify how many slides are included on each page and may refer to other layout options not focused on the number of slides.

Ultimately, selecting the slides per page option directly targets your goal, making it the correct choice for printing with three slides on a page.
