Often during installation there is a problem with hplip-*-plugin.run, it is available in the browser, but the hp-setup program cannot download it.

You can download it yourself to your computer and specify the path to it during installation.
Here is HP official site and unofficial

Thank you for your input.

I personally set up the printing via localhost:631 and the HP-Postscript-driver.

My problem started when I wanted to use the scanning facility of the printer. 'hp-plugin' didn't work. For hplip_3.22_6 I got around it by manually downloading the plugin and exchanging the devuan 'os-release' file with the debian one.

For hplip_3.22_10 I had to make changes to /usr/share/hplip/base/passwor.py as well. It does the job for now.

This issue started after last year's update Python3 and not only in Debian.
In my experience, the hp-setup GUI does not work.
At the same time, I managed to install the printer in interactive mode without any problems:

hp-setup -i

Problem:
There seems to be a mismatch between the devuan supplied Python3 and the HPLIP supplied python3 script. Hence the hplip-3.22.10-plugin.run will fail to install the plugin for the scanner.

Solution:
1. Make a backup of the files we change!

2. Change temporarily the content of "/etc/os-release" to:

PRETTY_NAME="Debian GNU/Linux bookworm/sid"
NAME="Debian GNU/Linux"
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

Also change temporarily in the file "/usr/share/hplip/base/password.py" the following:

On line 119 and 322
distro_name = get_distro_std_name(os_name)
to
distro_name = get_distro_name()

3. The command $ ./hplip-3.22.10-plugin.run will now install the plugin.

4. After the plugin has been installed reverse the changes.
