Antonio, your /etc/hp/hplip.conf file is missing.
Please reinstall hplip-common with this command:
# yum reinstall hplip-common
and try to reproduce the problem.

so I can't print anything thanks to a year-old bug. Ah well, maybe *2015* will be Year of Linux Desktop :(

What does 'ls -l /etc/hp' say? If you're running into this I think it means a config file has gone missing.

This bug causes that in some cases hplip is not able to write error message into log. This bug does not influence printing itself.

Might be if you're able to provide some info leading to identification of your problem.

aha, the gnome printer config program installed hpijs and hplip-common for me; I had to manually install hplip. Now I can print :)

[Jiri (jiri-redhat-bugs)]

Thanks Jonathan,

your problem looks like bug #1094530.
We probably need to move something from hplip package into hplip-common, but I've no idea what.

It'd be great if you could remove the hplip again and try to print something via printing troubleshooter [1]. Attach the output into bug #1094530. Then you can install hplip back. Thanks.
