Thank you for help. I've already tried standard technique for cores, but it doesn't work especially for hpcups. Ok, this is the bt for mine hpcups on working environment. Do you have any idea why this happens?

I'm getting similar thing with hplip 3.11.10:

Looks like binary plugin is bahaving badly:

ModeJbig::compress calls:

    HPLJJBGCompress (m_iWidth * 8 * m_iBPP, m_iLastRaster, &p, &myBuffer, &se);

where:

*(void **) (&HPLJJBGCompress) = dlsym (m_hHPLibHandle, "hp_encode_bits_to_jbig");

and

$ objdump -T lj-x86_32.so |grep hp_encode_bits_to_jbig
00000bd4 g DF .text 000000fe hp_encode_bits_to_jbig

Please download the latest hplip-3.11.10 from http://hplipopensource.com/hplip-web/install/manual/distros/gentoo.html and follow the instructions of installation. Connect the printer via USB and run "hp-setup" in terminal. It will ask for a plugin file to download. Once setup is done, you can print.

If you still face any issue, get back to us.

Please follow the installation steps in http://hplipopensource.com/hplip-web/install/manual/distros/gentoo.html and Connec the printer and run "hp-setup" to install a plugin file.

@Sarbeswar: this is caused by "Bug #666780: hplip-3.{9,10}, blob lj-x86_32.so dynamically resolves its "statically" linked symbols". Verified that - patching binary plugin fixed the issue (and I was already using 3.11.10).
