This is a misunderstanding of the vulnerability. The problem isn't with the print server. It is with the printer discovery mechanism, cups-browsed. That is the service that listens on the entire network, because it's designed so that LAN printers can advertise themselves to your system.

In that case one can disable it until it is patched assuming there isn't a udev rule that re-enables it. I stay clear of systemd these days so I don't know.
