Here’s how to print out Pope Benedict’s recent encyclical Caritas in Veritate in booklet form:Put the printout back into the printer. On most printers, you don’t need to flip it or rotate it.
This method should work for most printers. Some printers may require you to flip or rotate the paper in step 2. You may want to do a test by printing pages 1–2 of caritasinveritate-booklet-fronts.pdf, putting the printout back into the printer, then printing pages 23–24 of caritasinveritate-booklet-backs.pdf.
Thanks to American Papist
for the Word document on which this booklet is based.
