How To Batch Print on a Mac

I had a help desk call the other day. My client needed to print over 100 pdfs. I searched around for a decent solution and I found an awesome solution – mac only:
– open your printer queue. System prefs, print and scan and double-click on the printer.
– drag all the documents into the queue. Some docs will enjoy this experience (the pdfs were happy), but some may complain.
This is such and elegant solution!
