hplip fails to setup printer/fax/scanner correctly

[Hans-Christian Stadler]

Setting up a printer (scanner/fax/print) HP Color LaserJet Pro MFP M477fdw on Ubuntu 20.10 fails for all devices.

At the same time, the same printer autodetected by avahi, works (even able to show cartridge status).

hp-check output:
hstadler@asrock:~$ hp-check
/usr/bin/hp-check:685: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if 'getfacl' not in g and '' is not g and 'file' not in g:

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]
