Description david Cossé 2021-04-08 09:32:56 CEST
Theme name: Adwaita
Kernel version = 5.10.27-desktop-1.mga8
Distribution=Mageia release 8 (Official) for x86_64
CPU=Intel(R) Core(TM) i7-3632QM CPU @ 2.20GHz

I'm not sure this bug is related to this package anyway after a fresh Mageia 8 installation I wanted to add an HP printer. I used the Mageia Control Center to add printer. Packages install successfully, unfortunately I was not able to see my wifi printer and to add it. I restarted cups service without success, I reboot the computer then the HP logo appears, I tried throw that way but without more success anyway a more explicit message appears the suggest to look at the firewall configuration. Enabling to discover printer and scanner solved the problem.
I would suggest 
- to display this message when user want to add printer or
- to ask user to disable firewall for printer or scanner.

Thank you for reporting.
Something like this have crossed my mind too.

I regard this as an enhancement request.
Such are typically set against Cauldron.

Actually this is pretty bad.

Makes new users not finding printers.

Firewall configuration in
 In MCC > Security > Set up your personal firewall

Should user enable both "CUPS" and "Network printer/scanner autodiscovery"?

"Network printer/scanner autodiscovery" should be sufficient. Allowing CUPS would be required if you want to send print jobs from a different box to the CUPS server running on the box where you configure this, AFAICT.

Although I'm not sure why we don't allow outgoing connections, as "Network printer/scanner autodiscovery" is not about incoming connections ... ? Changing the default here to allow "Network printer/scanner autodiscovery" would improve the end user experience quite a bit IMHO.

Printer autodiscovery is ok on a trusted small lan. It's not ok on an
untrusted lan or in a large netowrk. For security reasons, it should not
be encouraged.

Having it on should not be a default.
