Comment 2 for bug 1814436

Thank you Brian,

I've;
sh hplip-3.19.1-plugin.run
and that completes, then I
sh hplip-3.19.1.run

and the last few lines of what I get;

Running 'sudo make install'
Please wait, this may take several minutes...
Command completed successfully.
Build complete.
POST-BUILD COMMANDS
-------------------
warning: CUPSEXT could not be loaded. Please check HPLIP installation.

What do I do next?
I have tried hp-setup but it says it is not installed,

Command 'hp-setup' not found, but can be installed with:
sudo apt install hplip

and then when I do that, I get;
Reading package lists... Done
Building dependency tree
Reading state information... Done
hplip is already the newest version (3.17.10+repack0-5).
0 to upgrade, 0 to newly install, 0 to remove and 65 not to upgrade.
