I have a book for a class on cd-rom. Is there a way I can print it out to use in class?

What format was the book saved onto the CD? If it was the pdf type file you could print the book out if the cd has not been blocked for print out of the material. Sometimes books are blocked from being printed out due to copyright laws.

You could try copying the CD onto your hard drive and seeing if you can print it out from your hard drive. Sometimes that works, sometimes it doesn't.
