I think Johannes Gebauer mentioned CocoaBooklet. This is a free OSX utility that takes page-oriented PDFs and produces booklet-oriented PDFs from them, which you can then print directly with the free version of Adobe Reader or with Preview. I use CocoaBooklet all the time and recommend it highly.
If you have the Finale mus files, you can also print to a booklet-oriented PDF directly from Finale. _______________________________________________ Finale mailing list Finale@shsu.edu http://lists.shsu.edu/mailman/listinfo/finale
