By Win2K, that's probably a gruesome hack for backwards compatibility
with DOS programs that translates that to the proper driver calls. It's
improbable that you're actually talking to the printer directly.

For the quick hacks, write stuff to a temp file and do system("print
path\to\file"). For the less hacky version, use the bindings to the
Win32API, or use a GUI toolkit - those tend to feature print support.
