[CentOS] Remote print problem -- LPD, IPP and other standard printer ports

[Todd Cary]

*Problem solved!

*It was the damn M$ Firewall on my wife's computer!  Yes, allow Printing 
and Fax was checked in the Exceptions, but for some unknown reason it 
did not allow the printing to go through.  Turned off the Firewall and 
the spooled pages came flying out!

Even though I know just enough to keep my Linux servers running 
(actually, once they are up I am able forget them until we lose power - 
then I need to power them back on :-) ), I know that somewhere in there 
is an answer.  Not so with Windows.

Thank you for trying to help with this....
