On the old Microsoft Powerpoint, I used to be able to change the slide design to a blank template and print it out in black and white. But ever since I got Microsoft 2011, I can now open pptx files, but I can't change the slide design to "Blank Template." I don't want to print out colorful slides and waste ink! I tried the options on the menu for changing slide colors, but it does nothing. How can I just make it plain white with black print? Note: these are files downloaded from my school's website for lecture. So am I unable to change the format because it's already made by someone else? Sorry. Microsoft Office 2011. Printing it in pure black and white would still be wasting ink because I tend to download presentations where the slides are usually a dark color with a light colored print. I want to simply make the slides plain.
