Have you tried just using Finder? Open a Finder window that has the documents that you want to print. Select and highlight all the files that you want to print by using the Command key. Then go to the menu bar and choose 'File' and then 'Print' -- I tried this and it worked to print several PDFs. They *did* quickly open in Preview, and I don't know how to prevent it, but just as quickly, Preview stopped showing the file and closed down. In other words, Preview opened only long enough to print the files, then closed down.
