I saw your message to Patrick that he forwarded on to the LPRng list -
have you had any luck in tracking down the cause behind the problem
described in number 5 (print jobs coming out on the wrong printer)? I am
having the same sort of problem, and was wondering what you may have
done to track it down or to at least narrow down the cause. Thanks.
