it took a while for me to find it, but: 1. open up tcp/6566 firewall 2. in mcc scanner make sure you give access to only a few ips, the "all computers" selection does NOT work. 3. add saned to the lp group if you have a printer+scanner setup 4. don't forget to restart the xinetd service manually afterwards
TODO: 3) i guess someone could add saned to lp group by default 4) and convert the saned xinetd to systemd too
