Thanks...that worked.

I have also been trying to get the return code and standard error.

How do I access these?

#!/usr/bin/python
import os
import subprocess
process=subprocess.Popen(['lpr', '-P' ,'raserlpr','/etc/hosts'],
shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

print process.communicate()
