Network printer detection -- avahi not included?

It makes no sense – either you don’t want avahi, and you should uninstall it altogether (thus effectively switching it off) or you do, and you need to enable it (and the vast majority of newcomers aren’t going to know this, so they’ll have to spend a bunch of time and energy digging around in the documentation like I did).

You started right, but in regard with how you idealize things, and you got very wrong about avahi

Pamac freezes while trying to remove avahi

Greetings, I am trying to remove some of avahi’s client apps (SSH server browser and VNC server browser). Running “pamac remove avahi” from shell hangs with the following message. CPU utilization is close to 100% when this happens. The only way to terminate is to kill pamac from another shell session.

Remove avahi package [is it possible?]

You can not remove Avahi without removing a lot of other packages. If you don’t need a GUI, you can remove Avahi. But probably need to set up your networking manually. If you don’t want to use it, disable and mask the services provided by the Avahi package. It is the closest thing to remove it. An Alterativ would be to build your own packages without a Avahi dependency.

Remove avahi package [is it possible?]

You cannot remove avahi it you use NetworkManager. You will have to use another connection manager or manage it in terminal.

Remove qt dev apps and avahi

No assumptions is made on the end users qualifications as developer. It is simply a matter of dependencies. You are welcome to remove them but please take a close look at the consequences before executing the actual removal.

More about avahi and understanding it

Really "under your control"?

Lots of things actually depend on Avahi for network discovery.

What is the need of Avahi Zeroconf/SSH/VNC

If you don’t know what they are for, I would trust the maintainers and keep them installed. None of them will be of use to “browse the internet”. Avahi, for example, is for finding local devices in your local network, like a printer. As the isos are not only for installing but also Live-usb which are very often used to fix your already installed version, I would hate to install of these program/libraries again and again.

Avahi-Daemon open network ports, is it safe to disable?

Those are unprivileged ports. They are perfectly safe. It’s not. It’s just a framework to help discover services available on the local network ─ e.g. a networked printer or scanner ─ without needing any manual configuration. You can disable Avahi if you don’t need it, but there’s not much of a point in doing so. It’s not a security hazard and it also doesn’t consume many CPU cycles. sudo systemctl disable --now avahi-daemon.service sudo systemctl mask avahi-daemon.service

That sounds like the Arch mentality leaking.
