cupsd should listen on ports but only on localhost:
# ss -nltup | grep cups
tcp LISTEN 0 0 127.0.0.1:631 0.0.0.0:*
users:(("cupsd",pid=30001,fd=8))
tcp LISTEN 0 0 [::1]:631 *:*
users:(("cupsd",pid=30001,fd=7))
If this is not the case you should put in /etc/cups/cupsd.conf
Listen localhost:631
Listen /run/cups/cups.sock
