View Full Version : [ubuntu] Troubleshooting a network printer--completely lost
May 10th, 2009, 04:03 PM
I've done a tiny bit with Samba, but have no experience with networked printers. There's an HP Business Inkjet 2200 in our office. I'm trying to print to it today, but while I don't see any errors, nothing's printing either. When I go to System -> Administration -> Printing, I think I see the printer I need, but the Device URl is listed as file:///dev/null. I click the "Change . . ." button, look under "Network Printer," and see HP Business Inkjet 2200. That shows a listing of IPP Printer and next to "Host" it lists 192.168.107.254:631. However, a coworker shows a completely different internal IP address for the printer I'm trying to use. I'm really stumped and don't know what to check from here.

192.168.107.254:631And when you try to add this as an IPP protocol printer, does it print?

I tried adding that as an IPP printer. When I clicked 'Verify,' I get an error saying "This print share is not accessible."

a coworker shows a completely different internal IP address for the printer I'm trying to use.I think I might try using the co-worker's URI in the setup for IPP printers. It should be approximately:

OK, I tried adding the printer that way. The icon shows up with a green checkmark in the printer configuration window, but the Printer State under properties lists "Stopped! unable to locate printer 'ipp'
May 10th, 2009, 08:14 PM
I don't even see 'printer state'! Is it set up similar to what I have posted?
May 10th, 2009, 09:16 PM
Yep, if you look right in the middle of your screenshot, you'll see "Printer State: Idle." Thanks for your help, but I'm going to try something different. I'll hook the printer up locally and see if I can share it to a Windows machine.

Pffft! I need a few more grinds on these greasy old trifocals! Thanks.

OK, I'm back fresh on this on a new days. Here's what I've determined.
1) I can print just fine to a different printer on our network, an HP Photosmart.
2) The one that's giving me a hard time is an HP Business Inkjet 2200 connected to a Windows XP machine and shared. A different Windows computer here in the office can print to it.
3) I'm getting confused by the two different ways to configure printers, the CUPS interface through the browser and the System -> Administration -> Printing command in Ubuntu. Are these different interfaces for doing the same thing or totally different programs?
What can I try from here? I appreciate the help; I'm a longtime power user, but I've got little education in networking and none in network printing.

Still nothing, huh? I also notice that when I delete this printer from the Printer Configuration Utility, it comes right back, so I'm presuming that Ubuntu is seeing SOMETHING on the network, however imperfectly. Are there steps I can take or logs I can look at to determine where the problem lies?

I just read this: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/286080 Especially this:
My current solution is to append the line " /etc/resolvconf/run/resolv.conf r," to /etc/apparmor.d/usr.sbin.cupsd. After that printing works fine.I believe the new line would go at the end of this part:
/etc/ssl/** r,Would you please try this, reboot and let us know?

When I print a simple text page, it still just sits in the queue saying "processing." I never did anything to set up this printer through Ubuntu; it just shows up on the network. I don't understand what the settings are SUPPOSED to be when I go in and look at the properties. I know the IP address of the other computer, but don't know what else Ubuntu needs. I've tried various combinations of 192.168.1.32:631/hp2200, with and without the port number, with "/printers" before hp2200. Could this have been set up improperly by another employee who runs Ubuntu on a different computer?

Could this have been set up improperly by another employee who runs Ubuntu on a different computer? Very doubtful.
You said when you delete the printer it reappears. Can you check the reappeared printer's properties and see what it thinks the URI should be? An IPP printer should be, approximately:
ipp://192.168.1.32:631/printers/HP_2200In most cases, a network printer will get detected and the configuration proposed in System -> Admin -> Printing.
Did you make the changes I suggested above? Any change in behavior?
I'm getting confused by the two different ways to configure printers, the CUPS interface through the browser and the System -> Administration -> Printing command in Ubuntu. Are these different interfaces for doing the same thingYes; one the GUI way and one the hard way.
You might also try to add the printer as a network printer and select Windows Printer via SAMBA.

I did make the changes you suggested to /etc/apparmor.d/usr.sbin.cupsd, but nothing seems to have changed.
My coworker has gone home for the day and I've discovered a little bit more. Here are the computers in question:
Dudley (my computer): Ubuntu 9.04
Nell (another computer on network, with HP printer attached and the printer shared): Windows XP
Snidely (coworker's computer): Ubuntu 9.04
Horse (printer): HP printer attached to Nell
Now that Snidely is shut down, Horse no longer shows up on my list of available printers. Why should Snidely have anything to do with it? Dudley is trying to see Horse, a local printer on Nell.
I tried adding Horse as a network printer and selecting Windows Printer via SAMBA, but when I click Browse, I'm not seeing any systems other than my own. I know I have networking set up at least partially correctly because I CAN print to Fenwick, a networked printer that's usually locked up in the boss's office.

Now that Snidely is shut down, Horse no longer shows up on my list of available printers. Why should Snidely have anything to do with it?The only thing I can hypothesize is that Horse is set up to share, as network printers should be. Snidley has incorrectly set the printer he sees on his computer to share. I'd guess you are seeing Horse not directly through the network, but through Snidley's share. In other words, a share of a share.
My coworker has gone home for the dayTomorrow, I'd check his computer to see if the printer is shared. It only should be shared on the computer or print server it's attached to. If you can stay late, you might shut down every computer except yours and Nell, the computer the HP 2200 is attached to and delete and re-install the HP 2200. Hopefully, the correct URI will be auto detected.
