System-config-printer : client-error-not-possible when add a samba printer

[Bill]

Googling this shows just about anything can cause this error. 

maybe it's as in this googled snippet:
"I believe I have fixed the issue. After playing around I realized that smbclient 
would complain that 'client plaintext auth' was disabled (my campus server needs 
plaintext for some reasom).

Adding the following to smb.conf and rebooting fixed my problem entirely:
client plaintext auth = yes
client lanman auth = yes

This may compromise security slightly (plaintext passwords are almost never a good 
idea). Please let me know if this fixes it for you. I'd be happy to keep investigating 
this if my fix does not work for you."

--or--
"To enable plaintext authentication, set 'client plaintext auth = yes' in the [global] 
section of /etc/samba/smb.conf."
