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).

| SUMMARY |
-----------

Please refer to the installation instructions at:
http://hplip.sourceforge.net/install/index.html

Done.

Please run "hp-toolbox" and go the Print Settings tab. You can set the "Brightness" option under "Printout Appearance" region there.

If this does not work for you, or you do not see the Brightness option, please try with hpcups pcl3 drivers. The ppd will look something like hp-color_laserjet_cm1312_mfp-pcl3.ppd.

Let us know the results once you have tried the above suggestions.

Thank you for your support towards HPLIP.

With hp-toolbox, the birghness doesnt seems to change anything... BUT, gamma was 1000 (the default value), i set to 1 and it's really fine, i can say perfect !

I think this default value should be considered as a bug.

Thanks for your support, very fast.

We have added your comments to our review list for future releases.

Sorry for the inconvenience and thanks for your support of HPLIP.
