[SOLVED] CUPS problem; can't add printer

Hello,

After a while of not using my printer I reconnected it printer today but found it didn't work with my CUPS config anymore..
I followed http://wiki.archlinux.org/index.php/CUP … CUPS_1.4.x, but to no avail.

I have a Samsung ML-1640.

When I goto http://localhost:631/admin and try to 'Add printer' I enter the correct user/pass but end up with a 'can't find page' error.
When using system-config-printer and pressing 'Add printer' nothing happens, but in the background the below traceback is shown.

I tried changing the default system group, for if the rootaccount would be locked (how to check if it's locked?) and assigned a user to it. But again, the same results.
Finally I completely removed cups, including config files and reinstalled, again to no avail.

Does anyone have an idea?
Thanks a lot!

Re: [SOLVED] CUPS problem; can't add printer

Hmmzz.. Just spend the last three hours getting my printer to work and it seems that the 'can't find page' error was simply caused by Chromium's inability to correctly show the CUPS interface. So installing Firefox and adding the printer through there simply fixed the problem.
Thanks

ps. the system-config-printer problem still remains..

Re: [SOLVED] CUPS problem; can't add printer

I also have problems to add a new printer via the CUPS-Interface using chrome. It behaves exactly as described by Bart6114.

When I goto http://localhost:631/admin and try to 'Add printer' I enter the correct user/pass but end up with a 'can't find page' error.

But when I first restart the server via the CUPS-Interface, I can add a new printer without further problems.
The steps are as follows:

1. Goto http://localhost:631/admin
2. Press the button "Edit Configuration File"
3. Accept with "Save Changes" and provide correct username and password
4. Add a new printer as normal.

The behavior is really strange, so I would like to exclude that this workaround only works for me.

The next step would be to clarify whether there is an error in CUPS, or Chrome. But if it is not reproducible on Firefox, I would almost accuse Chrome.

Perhaps this post will help someone.

Re: [SOLVED] CUPS problem; can't add printer

I can reproduce the "fix".

Running Chrome as well, but I'm almost positive I tried other browsers and got similar page errors before trying your trick.
