Color photos and images within Adobe Acrobat PDF and Microsoft PowerPoint slides can create very large print files that either take forever to print, or worse, it can cause the print job to error when printing and not print out at all. To avoid that, you can print your PDFs and PowerPoint slides as grayscale rather than color to reduce the size.
