You can do this with visual basic script. If Word is installed on the computer you can use the Word.Application class to open a hidden Word window and tell it to print. It would be something like this:
Code:
Set WordObj = CreateObject("Word.Application")
WordObj.Visible = False
Set WordDocument = WordObj.Documents.Open(WScript.Arguments(0))
WordDocument.PrintOut()
WordDocument.Close()
WordObj.Quit()
This script will take a single command line argument and print that file using word.
