Като цяло не виждам проблем всичко е инсталирано, кабелът работи (под Вин печати) lpg e ready но командите чакат на опашка. Някакви настройки в протокола на печат можеби гадая още.

Може би драйвера на е точен? През CUPS опитвал ли си.
Това Ubuntu има ли графична среда или е сървър?
hp-doctor ?
Код:
1. Make sure you have several python (aka python2) and python3 versions installed.
Check this thread if you wish to learn more.
2. Completely uninstall HPLIP,
as explained here and here.
3. Install HPLIP and its dependencies from Ubuntu 18.04 repository
At the time of writing it is HPLIP 3.17.10.
sudo apt install hplip hplip-gui hplip-data hplip-doc hpijs-ppds libsane-hpaio printer-driver-hpcups printer-driver-hpijs
4. Run hp-doctor with python3
For those like myself, running hp-doctor and hp-setup commands as is may not work with the error: cupsext could not be loaded. please check hplip installation message printed out in response; you need to specify python version and point at where the respective binary files are located using which command:
python3 $(which hp-doctor) Make sure nothing is missing; everything should have OK status.
5. Run hp-setup with python3
python3 $(which hp-setup)
