Printer stopped to work (/usr/libexec/cups/filter/hpcups failed)

[Marco Diletti]

After a system upgrade my HP Laserjet CP1215 stopped to work.

I tried to install/disinstall hplip, ghostscript-gpl, dbus and cups several
times, purging configurations files, without success.
I tried to re-run hp-setup after every installation, in order to install
the required propietary plugin.
I tried too to use old versions of each package, with the same result.

My distribution is a Gentoo, but i tried to use, other than the gentoo packages,
the source tarball downloaded from this site.

When i try to print something, using my unix account or the root one,
i receive in the Web GUI the following message:
"/usr/libexec/cups/filter/hpcups failed"

This is the output of hp-check command;

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the
HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies
are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro
supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball
has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode
will check both of the above cases (both compile- and run-time dependencies).

I don't know if the crash of hpcups with signal 11 concerns something (referring to
the error_log posted above).

I am desperate, thanks for your attention and patience...

Hi,

Thanks for reporting this bug here. Will try to have the set up of this lab in our lab and reproduce the same and get back to you on the same.

Regards,

Hello gutamkk, thank for the reply.

I found some interesting line in the system log file:

It sounds like a memory violation, but i don't understain why only me is involved.
