I have the same problem. Installed hplip today for my HP OJ 6958 printer
and blue color printed all over the page.
Package: ghostscript

This software comes with ABSOLUTELY NO WARRANTY.
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).
Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]
