HPLIP

Color reproduction on Color Lasejet 2550 is bad

Asked by Simon Gerhards

I have a color Laserjet 2550n.

The prints have a very bad color reproduction.
The driver has options for "CMYK Inks" and "RGB Color" but both don't have an effect.
Is there anything I can do about that?

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).

If possible please install the latest hplip.

Also from the hp-check I don't see any printer queues configured. Please run hp-setup to configure your printer.

Well, I removed the two configured Printers, removed the hplip version that came with the distro, installed the newest one and configured the printer with hp-setup.

Now the settings have an effect.

Thank you!
