Error installing HP printer 1020 plus plug-in

Solution 1:

During chat session we discovered the following.

The problem was caused by a mix of binary installed HPLIP 3.21.10 and deb-packaged 3.21.6 version.

So we found HPLIP 3.21.10 distribution by find ~ -name hplip-3.21.10.run - got /home/mathphy226/softwares/hplip-3.21.10.run. Then asked it for self-removal as follows:

cd /home/mathphy226/softwares
sh hplip-3.21.10.run --noexec
cd hplip-3.21.10
sudo hp-uninstall
sudo python3 ./uninstall.py

sudo apt autopurge
sudo rm -vrf /usr/share/hplip/
sudo rm -rfv ~/.hplip /root/.hplip

sudo apt-get autopurge hplip hplip-data hplip-doc hplip-gui hpijs-ppds libsane-hpaio printer-driver-hpcups printer-driver-hpijs

sudo rm -vrf /usr/local/share/doc/networkx-2.6.3

Then reboot to get deb-packaged HPLIP 3.21.6 reinstalled with

sudo apt-get -o Dpkg::Options::="--force-confask" install --reinstall --no-install-recommends --no-install-suggests hplip hplip-data hplip-doc hplip-gui hpijs-ppds libsane-hpaio printer-driver-hpcups printer-driver-hpijs

and manually downloaded HPLIP plugin by

cd /home/mathphy226/softwares
wget -c https://developers.hp.com/sites/default/files/hplip-3.21.6-plugin.run
wget -c https://developers.hp.com/sites/default/files/hplip-3.21.6-plugin.run.asc

to install it later with hp-plugin -i .

Additional note: according to official HP docs this HP 1020 plus printer needs HPLIP >= 2.7.10, so binary HPLIP is not needed.
