Know your color choices before you print.
When you start to print, PowerPoint matches your printer with default settings for color or black and white. See how to check and change those settings. And examine the fine differences between printing in grayscale and printing in pure black and white.
If the default black and white settings don't suit you, refine your grayscale settings using a special menu. Use this same menu to hide items on the slide that you don't want to print, such as interactive buttons or navigational arrows.
Discover another way to hide items that you don't want to print. There's a single command that will hide all background graphics, whether you print in color or black and white. You can also use it to hide a graphic only on selected slides.
