Once you have created a presentation, and your computer is connected to a printer, you can print a copy. Before you do this, it's a good idea to preview how it's going to look.
You can choose to print one slide per page, with or without notes, or format the page as handouts displaying multiple slides per page.
You can also change the page orientation, choose whether or not to print the background or skipped slides, or choose to download the printout PDF file instead of printing it.
