Link Transfer Fail message on remote printing

[fairfax@pclink.com]

Since upgrading to Potato, I cannot print from remote boxes on my network, I get a message "Link Transfer Fail."

I also note that in syslog, I see 

tcplog: printer request from brubaker.martinet
ippl: ICMP message type destination unreachable - bad port from localhost [127.0.0.1]

Also, auth.log shows
PAM_unix[16418]: authentication failure; (uid=0) -> scm\artin for samba service
M

Does anyone know what these messages mean?

Thanks,
