You're testing the wrong thing. Your python programme is doing the 
equivalent of this shell command:

  echo hello | lpr

Does that work from the command prompt? I suspect it will fail the same 
way as your Python programme, and when you have a working "lpr" command 
at the shell prompt, you will find that same command will work from 
within Python.
