Color printer cartridge flashes for HP deskjet 920c. Not sure I have to use a foomatic, cups, or simplified driver.Communications proclem with printer when I use HPLIP. Could be parallel port 0 not true. Printer worked 2 days ago, but now flashing red colour cartridge prevents HPLIP from send any commands to printer.

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).
