Not only is a
tremendous amount of toner wasted when students print them, but laying
down all that toner often causes our printers to jam. And it's pretty
hard for students to make notes on a black piece of paper.
To avoid this, open the presentation in Powerpoint and
Go to File -> Print ->. Under
the Color/Grayscale option select
Pure Black and White. then select Save as a PDF or Adobe Distiller as
the printer. Post the new file to Blackboard.
