I used to be able to scan on my gentoo box from an HP officejet pro on the network. This is now failing and i can see that the gentoo box is attempting to connect to TCP/6566 on the HP, but the HP is not listening on that port.
Test command is; hp-scan -dhpaio:/net/HP_Officejet_Pro_8620?ip=<ip address> Is 6566 scan attempt using the correct port? Nmap of the printer; PORT STATE SERVICE 80/tcp open http 139/tcp open netbios-ssn 443/tcp open https 445/tcp open microsoft-ds 515/tcp open printer 631/tcp open ipp 3910/tcp open prnrequest 3911/tcp open prnstatus 6839/tcp open unknown 7435/tcp open unknown 8080/tcp open http-proxy 9100/tcp open jetdirect 9220/tcp open unknown 53048/tcp open unknown
