Actually in this case (_writing_ text to a printer) I think you want the
Linux CUPS package for access to your remote printer, and then popen on
the 'lp' command (but use subprocess.Popen instead, that's better).

By the way, when you get closer to getting the above to work, you're
going to want to add a '\n' to the end of that string you are writing.
