After giving up on Mac Preview's glitchiness, and Acrobat's complexities, I grabbed this because it seemed like a clean, simple way to batch-print PDFs. And it IS, except for the fact that with duplex printing, it runs all the multi-page files together. So, the result: with many files, the first page is on the back of the previous file's last page. Not good!
