install HPLIP-3.22.2 on Linux Mint 20.3 failed

Follow the instructions in the first post at

https://answers.launchpad.net/hplip/+question/700478

I'm assuming that the important entry on that thread is entry #9.
I used this command.
It completed the installation.
I tried to perform a scan afterwards, starting the HP device manager.
I responds (as before) with a plug0in installation is need.
I followed the dialog but at then the plug-in installation failed.
The final entries in the terminal windows are:

<<<
Plug-in version: 3.22.2
Installed HPLIP version: 3.22.2
Number of files to install: 64

note: Using PyQt5
qt5ct: using qt5ct plugin
Plugin installation failed
error: Python gobject/dbus may be not installed
error: Plug-in install failed.

Done.
error: Failed to install Plug-in.
Either you have chosen to skip the Plug-in installation or entered incorrect Password.

Done.
>>>

If necessary I could provide some screenshots and the full terminal output.
(How can I attach files to this issue?)

No success yet.

TIA

PS: Interestingly, on my laptop with Linux Mint 20.3 as well the scanning with HPLIP works fine. (HPLIP-3.14.1)

Printer make and model, please?
USB connection?

Ethernet connection. Printer HP MFP1536dnf

HPLIP (scanning) is working on a laptop with Linux Mint 20.3 & HPLIP-3.14.1, same printer.

Thanks

Any updates available on this item?

well maybe 15 days is not enough.

I needed to scan some documents and I was forced to use a WIN laptop (which is a pain on it's own).
I still cannot scan on my Linux box.

Hopefully someone can provide some help.
Thanks in advance.

I still wasn't able to successful install (and use) the hplip software.
I downloaded the latest version hplip-3.22.4 and executed the shell script.
I had all previously installed hplip versions removed during the execution of the script.
After install was completed I launched hplip for scanning with HP M1536dnf.
It appears that it can't connect to the printer (xsane 0.999) even though I can print pages.
Than it says it need to an additional driver plugin is needed why subsequently fails.
Below are screenshots of all steps I went through.

Perhaps one of the hplip team members can look it this problem?

Thanks in advance

PS. Do I perhaps have to install an older version as 3.22.4?

What exactly happens if you try the following (already mentioned in the first comment):

For manually installing the plugin download the *.run file in the same version as your HPLIP installation from https://developers.hp.com/hp-linux-imaging-and-printing/plugins and install it by executing the command
sh ./hplip-3.22.4-plugin.run
("cd" into the right directory first and replace the version number accordingly)

Hallo Manfred,

As i mentioned in my previous posting I executed the specific, downloaded script .
(... I downloaded the latest version hplip-3.22.4 and executed the shell script. ...)

The script finished to the end without any error messages.
As part of the script I removed the 'old' version of the software as requested by the script.

When I'm launching hplip to scan (after hplip launched xsane) it's asking for another plug-in install.
Please see screenshot #2 and #3.

It's like going in circles.

I'm desperate to get this scanning going.
HELP - HELP - HELP.

TIA

PS. Should I perhaps try an older version of hplip?

Don't confuse the hplip software installer hplip-3.22.4.run and the plugin installer hplip-3.22.4-plugin.run

ah grrr.
Than I will download and run the hplip-3.22.4-plugin.run script

Finally.

It seems that was the solution for the problem (to run hplip-3.22.4-pligin.run).
Now he scanning works.
Thanks to all who helped (-> Manfred).

Only one questions remains:
How can I scan a document in DIN-A-4 format and not in letter format?
under the menu entry "Preferences - Setup -> Copy" there are fields for Paper geometry; are these the fields to change for DIN-A-4?
