Dual boot/970cse: Colors great in WinXP, bad in Ubuntu (no cyan at all).

Problem is on Ubuntu side only; All color printing is 'pink', seems to only contain magenta/yellow (black seems fine).

I have updated to hplip 3.9.8 and it didn't change anything. Removed printer and reinstalled using hplip (discover), no custom settings...

Output of hp-check -t:

This is free software, and you are welcome to distribute it
under certain conditions. See COPYING file for more details.

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).
