Hi Bryan,

Thanks for the reply. I never would have figured that out. However, I 
have something strange going on. The printer name is "Epson". When I do 
an 'lpstat' I get 2 printers listed (Epson-12, Epson-13) but neither is 
"Epson". When I look at 'system-config-printers' I see just the printer 
"Epson". If I issue the command

sudo lpadmin -p Epson -o auth-info-required=none

I get no error (which I expected since it does not seem to exist) but 
neither does anything change.

I am guessing that my problem is related to the printer not showing up 
in 'lpstat' but I have no clue where the 12 and 13 are coming from or 
what could be wrong. Did I perhaps mess up my cups.conf with the changes 
I made?
