can you edit your post and add three backticks ``` above and below the pasted terminal output ?

that way it will be formatted properly and be readable for all of us :wink:

Ok, done. Note: problem is with Ubuntu Mantic 23.10 installed from ISO dated 2023/07/22 Note: printer works fine same PC different partition with Ubuntu Mantic 23.10 installed from ISO dated 2023/07/17

Thanks for fixing!.. I guess @till.kamppeter can give hints regarding the cups snap

You mean I have to contact till directly? how can I do? Thank you

@corradoventu you do not need to contact me directly. @ogra has mentioned my user name and then I get a notification.

First, all components of the printing stack are in Snaps, so most infrastructure which was created for Debian packages will not be there any more, like ubuntu-bug for example. This does not mean that modern, especially also immutable, distros do not use bug trackers any more. they are still there. Probably later on we will add new tools to facilitate bug reporting for Snap packages.

AFAIK the HPLIP Printer Application is pre-installed in Mantic, so if you install Mantic from a current ISO, you have it already installed. If it is missing (run snap list | grep hplip-printer-app) install it from the Snap Store via

sudo snap install hplip-printer-app

then take a web browser and go to “http://localhost:8000/”, “http://localhost:8001/”, “http://localhost:8002/”, … These are the web interfaces of installed Printer Applications. Check on the upper left whether you are in the one of the HPLIP Printer Application (this will be facilitated via the Printers module of GNOME Control Center soon). Then click “Add Printer” in the upper right and set up your printer.

On Mantic i installed successfully my printer from localhost:8003 but a normal user will try to install using gnome-control-center and fails. Thanks

Changing GNOME Control Center to support the CUPS Snap is in the works See my comments on the Ubuntu Discource thread.
