Personally I'd just have a shortcut to open the word file which has a macro that autostarts when the file is opened. It will open up the word interface but it would be a matter of double clicking the shortcut, word will open, macro will run, file will print with requested settings, word will close again. You can rush round the room whilst it's doing that.
You could probably script that in VB.net using something like this https://stackoverflow.com/questions/10440740/how-to-print-a-word-document-without-opening-word
