<p dir="ltr">I had similar issues, i think i'd accidently clicked something that stopped ubuntu from updating configuration files in /etc when it did updates.</p>
<p dir="ltr">Needless to say that caused various issues similar to what you are experiencing and little tweaks here and there to fix them started to become to numberious, so I just reinstalled.</p>

<div dir="ltr">Hi all,<div>I've generally been quite impressed with how simple printing on Linux turns out to be, but at the moment "it's not working". I've investigated/asked for help to the extent that I can, and can't get to the bottom of it, so was wondering if you can help!<div>

<div><br></div><div>== Possible errors and debugging ==</div><div><br></div><div>At one point I thought that the problem might be with permissions in /var/{log,spool}/cups and have done some chgrp, probably between lp and lpadmin. Nothing has fixed problem obviously.</div>
