I know this is and old question, but i was faced with the same problem recently and none of the answers worked for me:
After searching a little more i found this: http://www.columbia.edu/~em36/pdftoprinter.html.
It's a simple exe that you call with the filename and it prints to the default printer (or one that you specify). From the site:
PDFtoPrinter is a program for printing PDF files from the Windows command line. The program is designed generally for the Windows command line and also for use with the vDos DOS emulator.
To print a PDF file to the default Windows printer, use this command:
PDFtoPrinter.exe filename.pdf
To print to a specific printer, add the name of the printer in quotation marks:
PDFtoPrinter.exe filename.pdf "Name of Printer"
If you want to print to a network printer, use the name that appears in Windows print dialogs, like this (and be careful to note the two backslashes at the start of the name and the single backslash after the servername):
PDFtoPrinter.exe filename.pdf "\\SERVER\PrinterName"
