Does driverless printing supports ink level for most HP printers? For HP 2778 printer, Ubuntu shows ink level, Debian Testing does not

I have a HP 2778 AIO printer which is working fine in both Ubuntu 22.10 & Debian Testing which I am dual booting. Both the OS uses driverless tech, though hplip also installed.

Ubuntu 22.10 shows the ink level using system-config-printer>properties:

While Debian Bookworm (testing) does not show in system-config-printer>properties.

How do I configure to get ink levels displayed in system-config-printer in Debian?

Are both environments using the same driver?

Code:

lpstat -t

Code:

sudo egrep -i "name|model|filter" /etc/cups/ppd/*

Yes. I ran the commands and diff output showed both are the same.

This is the output of lpstat & grepping of /etc/cups/ppd/ in both distros:

Also, system-config-printer is of a recent version (1.5.18) in Ubuntu. While, Debian Testing has got only system-config-printer version: 1.5.16-1.

I doubt that the configuration utility version makes any difference here.

I see you are getting help from
https://askubuntu.com/questions/1437...0-wirelessly-h
and

As the discussions seem to have progressed further there I'll jump away from this. Good luck.

No progress in case of Debian. askubuntu post was for Ubuntu 22.10, which is working fine. Not so with Debian Testing, though. Ink levels are not showing.

If you want an accurate ink level on HP printers you might try the hplip tools since they are explicitly designed for management of HP printers.
