HELP -------- Can't print using 3.3 Mini

[Ron.W]

What I do know about this already :

The backends are tiny little programs which transfer the printing tasks. If they are not present, you can't print or access the webinterface. So you will probably look for them:

enter with root-privileges in a console window
ls -l /usr/libexec/cups/backend

For example, my one shows me

lrwxrwxrwx 1 root root 26 17. Apr 04:30 beh -> //usr/lib/cups/backend/beh

Sorry, if backends are missing in your system, I have really no idea how to install them, since I am new to sabayon myself. You'll have to post the results and wait for someone who better knows about all this...

Just an idea: Maybe you can emerge them seperately.

Well, here is what that command came up with...

I have to admit, I'm a little confused by now.
On the one hand It seems you have all the backends installed correctly, but on the other hand cups tells you the lpd backend doesn't exist.

It looks to me like a case of misconfiguration rather than one of missing executables. To get an idea which files are to be configured in order to make your backend work, have a look at:
http://www.linuxquestions.org/linux/ans ... _Slackware
They describe in detail, which files are involved, and where these are located; take this pdf-backend as an example only to check and understand your lpd-backend.

Thx Ron. I don't have enough experience to figure this out. I guess I don't get to print from Sabayon. Maybe a reinstall would work? I just don't have a clue...

[Ron.W]

you could try in a console window with root permissions:

tail -f /var/log/cups/error_log

(or just look into the error-log using a texteditor)

maybe you can get some additional information from this.

[dnagel53]

Well, there are some interesting things in that error log. I looked at the entire log and see a lot of unauthorized responses, even though I used the root password when asked. Here is the result of the tail command, I notice that I no longer have any filters?

Full reload complete.

Looks like your cups-server is working already.

This means for me, that you should be actually able to connect to the cups http-interface. Try it again, please. Check also your proxy-settings (firefox has its own settings in a menue). Maybe localhost 127.0.0.1 isn't excluded from proxy and your browser asks any name-server on the internet for this adress... Try explicitly 127.0.0.1 instead of localhost... Try it also in Konqueror, or in any other browser you have installed. This is what I would do next if I had this problem.

Sorry, I don't even have an idea what is a filter here. But I understand I'll have to read more about it

Ron.

[dnagel53]

I still get 404 Not Found in Konqueror and Firefox using http://127.0.0.1:631. I guess if I want to print I may be faced with a reinstall. Not what I was looking forward to at this point...

[Ron.W]

The last thing I can advise you to do is: re-emerge cups completely. Maybe something went wrong the first time. I've read somewhere missing pages and filters are usually a sign of bad installation of cups-package.
But I never emerged anything until now in a gentoo-style system like sabayon myself (if this was debian with apt-get i could give you some additional hints...)

I really hope someone else will step into the breach and tell you what to do now.

Ron.

[dnagel53]

Well, I had hoped that someone else was able to jump in on this...
Oh well, I guess it is time to do something different. Even the x86-64 version does this.
