I don't know about other browsers, but Firefox's print dialog offers the option to fit multiple pages onto a single sheet natively. You can just print to PDF (or paper directly) in that manner.
Do you plan on cutting up all your quarter sheets and rebinding them? Because if you are expecting to fold the printouts as-is and have the pages in the correct order, you'll need a slightly more clever solution.
Apropos of nothing, Inkscape (free, open source) does a very competent job these days of importing .pdf's, at which point you can scale, rearrange, or otherwise edit them however you see fit. This will be tedious, but will allow you to do basically anything you want with the content.
