From micros50 at verizon.net Wed Feb 10 20:38:31 2010 From: micros50 at verizon.net (Micros50) Date: Wed, 10 Feb 2010 15:38:31 -0500 Subject: Printer Stopped Working Message-ID: <1265834312.16677.14.camel@manhattan.ruffe.edu> Hello, I have a Hewlett Packard B209 printer connected via wireless ethernet to my LAN. For the past several months everything was working fine. At l;east 3 different computers running Fedora 11 and 12 had no problems seeing the networked printer and printing to it. Then all of a sudden everything went kaputz. I think it happened after a recent routine upgrade via YUM. All of a sudden none of my computers can access the printer. It seems to show up as a valid networked printer but, I cannot get it to print. If I send a document to the printer I get the following message. "/usr/lib/cups/filter/hpcups failed" I cannot even access any administrative functions top pause or restart the printer, nor can I print a test page. I disabled my firewall and SELinux but unto no avail. It just sits there dumb, like it's there but not there. Up to a couple days ago it was working flawlessly. I attached a copy of my cupsd.conf file. If any further diagnostics are needed I can furnish those as well. Any and all help appreciated. Thanks in advance...

Thanks in advance... First, try to ping your printer, both by name and by IP address. If you can ping via IP but not name, then you may be affected by: There was an update to both F11 and F12 that can affect you if you are running BIND (named) on your machine. It has to do with the dnssec-conf RPM. Do an "rpm -q dnssec-conf". If you get a result that shows either 1.21-3.fc11 1.21-7.fc12 then "yum downgrade dnssec-conf" and then "service named restart".

I can ping the printer via it's ip address. I cannot ping by name and, I am not running bind nor is dnssec-conf installed. This problem is also network wide because none of my machines can print anything anymore. I still get the message "paused /usr/lib/cups/filter/hpcups failed" And CUPS administration won't let me unpause the printer nor carry out any administrative function.

Try to use the ip address and see if you can get to the printer via a browser. Also if possible can you get the printer to print out it's configuration ? I've seen other printers "lose" the network configuration.

What I did was to open the CUPS configuration dialog and delete the printer. Then I let CUPS discover what printers I have on the network.

Entirely possible that the ppd file or the identification URL for the printer changed. My guess is a hal or udev update buggered things. I've had locally-connected (e.g. USB) printers go offline after a hal update. I simply added them again and the new definitions worked a treat. The old definitions remained, however, and THOSE iterations of the printers were marked as "unplugged or turned off". Weird. So, I just deleted the old iterations and we're back to normal. I don't recall this affecting network printing, but my printers are all directly connected to my server and the network nodes print to the server's queues, not directly to the printers. Anyway, glad you got it sorted and sorry I wasn't more help. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer ricks at nerd.com - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - LOOK OUT!!!

Not to worry, actually you and Ted helped a great deal. Now that you mention it being a hal or udev issue and thinking back to some of the things I was noticing as I diagnosed the problem I think it may very well have been a hal or udev issue. I'll definitely keep that in mind in the event I should have any future or similar issues with the printing. Much thanks... Ciao John
