I recently had to print some of my notes - already in Org mode - for a meeting. After going through numerous options including reformatting in LibreOffice, pandoc, HTML, etc etc I discovered that org mode can export the documents to PDFs that look better than anything else.

Unfortunately, I don't have the config options that I used any more! I changed some fonts and drastically reduced the margins. And some places in which underscores were used had to be escaped as the PDF export interpreted underscores as being subscript.
