Cups does not get installed by default in Qubes, right?
I think it's not all that important to have print by default capabilities in Whonix-Workstation. And would advice to do that from another VM anyhow.
I don't like that it's creating a local TCP listener. When installed, even runs by default in Qubes TemplateVMs.
Any voice against removing cups from default Qubes-Whonix installation? @marmarek
