A little more searching lead me to a post of some one with the exact 
same problem. A user responded back:

think there are two possible solutions:
Try first: Set an allowed user
[localhost:631 <http://localhost:631/printers/>] click on `Set allowed 
users` and type in the names of the users allowed to use the printer. If 
your login name is john and you also want to be able to print as root 
type:root, john

Second (I had this problem):
[localhost:631 <http://localhost:631/printers/>] click on `modify 
printer` and choose for Device: LPT#1

They said to use the Assistant to do this - in Debian Etch. Looking at 
the first possible solution, how do I do this as Im not really sure what 
this is referring to.
