@FeRD I tried all your suggestions, but no luck. But something must have been broken in my Manjaro OS because after a current system update and a new download of hplip-3.25.2-plugin.run, the plugin install went nice with as result: [xyz ~]$ cd Downloads [xyz Downloads]$ sh hplip-3.25.2-plugin.run Verifying archive integrity... 100% All good.

Running tty in xfce4-terminal prints /dev/pts/0 Nevertheless, the script trips over -title. In xterm the installation is successful but then I receive the complaint that this hplip and my version of Manjaro are incompatible. But that is a whole different issue. I was trying to install hplip from SourceForge because it contains hplip-plugin. In Manjaro I used the gui Add/Remove Software to install HP Device Manager (hplip) 1:3.25.2-1. That succeeds fine and printing via wifi to the local network printer...
Thanks @FeRD. I'm using Manjaro 6.12 with xfce4-terminal version 1.1.5 in which I run sh hplip-3.25.2.run. This results in the error message Unknown option -title. Above option 1 is not applicable. Will try installing xterm and report back later.
The script of hplip-3.25.2.run contains 2 lines where the terminal is called with the option -title (single hyphen). The execution is aborted on this. I think the option should be --title (double hyphen).
