I have a scanner, but no printer.

Do you have CUPS installed? The problem is that cups-browsed, the service
for dynamically discovering printers on the network, is a little too
trusting of the responses it receives. Does

    ss -nlu sport = 631

show any listeners on UDP port 631 on your machine? If so, you can stop
and disable cups-browsed with

    systemctl disable --now cups-browsed.service

and then the above “ss” command should show nothing.
