I installed hplip-3.22.6.run, downloaded from the HP website. I noticed to late that my Ubuntu (20.04, Desktop) has a package for this.
Now I would like to install it again from the Ubuntu package, together with the gui, but I can't uninstall hplip.
I tried
sudo hp-uninstall
as written here: How to install latest HPLIP on my Ubuntu to support my HP printer and/or scanner?
but it just says "hp-uninstall not found".
How can I uninstall it?
