[h-e-w] How do I print to an IP address printer from emacs?

[tpmjohnson]

                  
I
am a Vista user and new to emacs (23). Whenever I try to print the current 
buffer
with headers I receive the error: 'Opening output file: permission
denied, c:/xx.xx.x.xxx' where xxx is the ip address port name of the
current default printer. It seems like it is trying to print to a file
named xx.xx.x.xxx instead of to the port? I have read through the various wiki 
entries but none of the suggestions seem to work.? Any ideas on how to change 
this?
