doPDF is a useful download for professors who wish to post any kind of .PDF files. doPDF will also convert only the handout notes of .PPT slides, instead of the whole presentation, for the students. doPDF acts as a print driver but produces a .PDF file instead of sending your document to the printer. You then can upload the .PDF file to Moodle and into your course.
