description:Hints and configuration for CUPS
title:Common Unix Printing System notes

- check your local .cupsrc

- The server has to be browseable for lpstat and lpstat.cups to work

- Connection refused could mean that you are connecting to the wrong server.

- The -h arg to lpstat does NOT override .cupsrc

- It is best to avoid lp and lpr and just use kprinter

- If your non-root printing manager can't contact a running cups server,
then it is probably an access list problem.
