We do this as well, but didn't want to call up the program for printing. So we converted the PDF to PCL using GhostScript, then send the PCL directly to the printer using TCP. Of course this doesn't work with USB printers, although a similar serial method could work I suppose. And the printer has to support PCL.
This method is truly silent, no additional windows pop up and it's pretty quick as well. If interested I could find the methods and give you a quick rundown.
