You can print one slide per page or use multiple slides per page by selecting “Handouts.” Choose whether you want to print in color or grayscale and if the slides should be collated.

If the printouts are just for audience reference or handouts during an event, you'll probably want to skip the notes and print multiple slides per page to save space and paper.

To print a large image or poster on multiple pages, split it into different parts. You can use MS Paint, PosterRazor or The Rasterbator.
