The firewall will only watch Internet to LAN traffic so the printer is likely just co-incidence :)

 

If you have strange RaLink stuff on the LAN then deffinately look at investigating what these are, RALINK is a network card vendor, usually for WiFi cards

 

this is silly but printer was seen after network refresh and printer network icon is stable, alive and kicking sorry still don't know what to do RalinkLinuxClient and phones that are not mine perhaps I'll start with changing my password in tp-link config make it 20 char. instead of 10 thank you
