HP Envy 4524 All In One - Device communication error - code 5012;

[Charles Vine]

Situation:
Ubuntu 20.04 LTS after fresh install, NOT upgrade on desktop (had 16.04 LTS before). Printer was attached during fresh install of 20.04 LTS and internet connection, third party downloads ticked.

Bug description:
USB connected HP Envy 4524 All In One is recognized multiple times as printer but does not print, scans occasionally but unreliable in getting recognized by 20.04 LTS.

Additional Information:
HP Envy 4524 All In One works flawless with Ubuntu 18.04 LTS on Laptop. Worked flawless with Ubuntu 16.04 LTS on the desktop used above.

Steps taken so far:
De-installed/purged hplip 3.20.3 as sudo hp-check -i showed multiple errors and missing dependencies.
Installed hplip 3.20.5 from the HPLIP site and ran the script which resulted in compiling and installing the printer with nil errors running sudo hp-check -i. However, after reboot Device communication error - code 5012 re-occured (current hp-check log attached).

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]
