It does? This command doesn't exist on my machine. It's not a standard
part of windows.

Just to check though, are you 64-bit windows, and 32 or 64 bit python?
(To find out what kind of windows, go to the system control panel - to
find out if python is 64-bit look at the value of sys.maxsize, it's
2147483647 on 32-bit systems and 9223372036854775807 on 64-bit)

If all you want to do is print a text file, see
http://www.robvanderwoude.com/printfiles.php - these commands may not
let you do whatever you're trying to do with that IP address though.
