Yes and no. From the point of view of the command 'lp -d ... job' issued
directly on the server you are the user. When the command is issued from
another machine on the network you (the administrator) are not a user.
When you (as administrator) advertise your printers you are said to
share them. Users use your shared printers - they do not cause them to
be shared. Your generosity is in serving up these printers.

That makes your machine a server, Switch your machine off. How happy
will your users be? Argue your way out of the complaints you will get. :)

Just a normal misconfiguration. Tell them not to do double filtering.
It's evil and completely unnecessary.
