<div class="moz-cite-prefix">Hi Hakim,<br>
<br>
I've had similar problems to this; if I remember correctly it was
something to do with CUPS having chosen the wrong driver for the
printer. Something you might want to try is: if you open up your
web browser and type 'localhost:631' in the address bar you should
get to CUPS's web administration interface.<br>
<br>
From there, click the Printers tab, click the name of the printer
that you're currently trying to use and select 'Modify Printer'
from the drop down Administration menu. On clicking the continue
button several times you should get to a screen where you can
change the driver that's been assigned to the printer; probably
best if you make a note of whichever one is currently assigned
before changing anything.<br>
<br>
Something else that might give you a good hint is if you look the
model number of the printer that you're trying to configure at
<meta http-equiv="content-type" content="text/html;

Hope this helps! Good luck.<br>

<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>I print a document from a GUI app. This problem happens
to x2 printers I have in my list (DoES's networked Laser
printer, and my dad's USB-connected Laser printer), both of
which I have successfully printed to before on this
machine. </div>

<div>Gnome's task bar shows a printer icon. When I click on
this I can see the print queue for the printer I've printed
to. It starts off with Status = "Processing: Not connected"
and after a minute or so this changes to "Held". The
document never prints.</div>

<div>I've checked the error in <a moz-do-not-send="true"
href="https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1088448">https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1088448</a> and
it looks like the SystemGroup entry has been removed from
cups, but not from the cupsd.conf file. I've commented out
the entry and re-started Cups, but that didn't fix the
problem. Bah.</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>
<div><br>
</div>
<div>=== Me cargo culting Things I Don't Understand ===</div>
<div><br>
</div>
<div>So, um, I have an SSD. I cargo culted some stuffs about
tuning for SSD, including adding these lines to /etc/fstab</div>
<div><br>
</div>
<div>
<div> tmpfs /var/spool tmpfs defaults,noatime,mode=1777
0 0</div>
<div> tmpfs /var/log tmpfs defaults,noatime,mode=0755
0 0<br>
</div>
</div>
<div><br>
</div>
<div>It occurred to me at some point that if Cups had created
paths it needed on *configuration* rather than init, then
the next time I reboot, it might be unhappy...</div>
<div><br>
</div>
<div>I've commented out those lines, rebooted, and attempted
to rerun configuration by running:</div>
<div><br>
</div>
<div> sudo dpkg-reconfigure cups</div>
<div>
<div> sudo dpkg-reconfigure dbus</div>
</div>
<div>
<div> sudo dpkg-reconfigure hplip</div>
</div>
<div><br>
</div>
<div>Again, these don't seem to have helped.</div>
<div><br>
</div>
<div>= HAYULP? =</div>
<div><br>
</div>
<div>I'd be very grateful for any suggestions for what to do
next!</div>
