kubuntu printer configuration failure

[buzzmandt]

I'm getting a printer fail when trying to configure the printer in kubuntu oneiric. 2 of 2 computers have this so far, anyone have any suggestions for me?

Re: kubuntu printer configuration failure

use the web host to admin.. open a browser and open "localhost:631" this is the way to admin cups, when prompted for a usr/pass its the one that you use to log in your machine.

its a good thing to know cause it will work on any system with cups

Re: kubuntu printer configuration failure

I'm running Natty, but I ran into the same printer problem today.
Is there a known fix for this? at the moment I can't print at all.

I tried the localhost:631-thing in FF and rekonq but not success. I get:
Unable to connect
Firefox can't establish a connection to the server at localhost:631.
What am I missing?

Re: kubuntu printer configuration failure

localhost:631 connects to cups. Do you have cups installed?

CUPS an acronym for Common Unix Printing System

[Chopstick]

Re: kubuntu printer configuration failure

Yes, I have CUPS installed... and I had printers working before.
They stopped working yesterday, and now I have this problem described above.
I think there have been some CUPS or printing related updates recently...

[Chopstick]

Re: kubuntu printer configuration failure

I think localhost:631 probably doesn't work because I'm printing (was printing...) on a network printer through a print server. When I enter http://our.print.server:631/printers/ I can view the list of printers and their print queues, but I can't configure anything or submit jobs. I suppose that's blocked in our network. Is there a way to configure a network printer in a different way? (as a workaround)

[buzzmandt]

Re: kubuntu printer configuration failure

if you're fully updated system settings/printer configuration should be working now.

Re: kubuntu printer configuration failure

Hm... today I only had updates related to samba... my system is fully updated, but the problem persists.
There was no update related to CUPS, KDE, or python recently.

On the server, you need to enable (via a tick box) "Allow remote administration" It's on the Administration page under Server Settings. If the server is headless, edit /etc/cups/cupsd.conf (on the server) and find this section:

<Location />
 # Allow shared printing and remote administration...
 Order allow,deny
 Allow @LOCAL
</Location>
<Location /admin>
 # Allow remote administration...
 Order allow,deny
 Allow @LOCAL
</Location>
<Location /admin/conf>
 AuthType Default
 Require user @SYSTEM
 # Allow remote access to the configuration files...
 Order allow,deny
 Allow @LOCAL
</Location>

Where mine says Allow @LOCAL yours should also.

Re: kubuntu printer configuration failure

If you can't connect to the CUPS interface at localhost:631 You may have an error in your /etc/hosts file. To see if this is the problem try 127.0.0.1:631 instead. If it connects using that URL the check the /etc/hosts file to see if it contains a line like this:

127.0.0.1 ubuntu64 localhost.localdomain localhost

The name of your computer should be where mine says ubuntu64.

Re: kubuntu printer configuration failure

This is what my /etc/hosts looks like (komputer being my computer name):

127.0.0.1    localhost
127.0.1.1    komputer

# The following lines are desirable for IPv6 capable hosts
::1   ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Re: kubuntu printer configuration failure

Looks OK. That is not the problem.
