Hey Aure....
That's an excellent suggestion, and one I've considered as the document has grown in length. My only hesitation is that the text will be so
small. And because standard paper sizes are different in different countries, there's no way to format it that would be equally user-friendly all over the globe.
That said it's relatively easy for you to print this PDF on any size paper as a 2-up (meaning 2 document pages per sheet of paper), front and back document, albeit not one that could be stapled and bound. When you have it open in Adobe (or whichever reader) go to PRINT SETUP > PROPERTIES, and then change PAGES PER SHEET to 2. This will give you 2-up printing. Then, opt to print only odd numbered pages which will give you all the fronts of the pages , then put that stack pack into the printer and run the even pages.
What you end up with, though not bindable, uses much less paper and is foldable at the center seam. But the text will be small.
Hope that helps.
