Multi PDF Printing for Macintosh 10.9 and higher

1. Open System Preferences.
2. Select Print & Fax.
3. On the left, you’ll see the available printers. Select the one you want to use.
4. Now, on the right, you’ll see an option that says “Open Print Queue.” Click it.
5. This will open your printer queue. Simply drag the whichever files you want to print from your computer into         the bottom portion of the print queue box.

That’s it. Certain file types will open their application in order to print. For example, when I dragged an Excel file to the queue, Excel quickly opened and closed.
Saves a bunch of time.
