printing can nolonger athenticate between boxen on my lan under Precise

[Grizzly(Francis Smit)]

I used to be able to print on my lan now I cannot since I upgraded my boxen to precise

1).
root@rakbat:~# lsb_release -rd
Description: Ubuntu 12.04 LTS
Release: 12.04

2).
root@rakbat:~# apt-cache policy samba
samba:
  Installed: 2:3.6.3-2ubuntu2.1
  Candidate: 2:3.6.3-2ubuntu2.1
  Version table:
 *** 2:3.6.3-2ubuntu2.1 0
        500 http://au.archive.ubuntu.com/ubuntu/ precise-updates/main i386 Packages
        500 http://security.ubuntu.com/ubuntu/ precise-security/main i386 Packages

3). I expected to be able to print from one Precise box to another Like I did under 11.10 oneiric

4). got a authentication fail many times

I have also tried to reset the samba passwd on the box with the printer on it got this:

username@pern:~$ smbpasswd
Old SMB password:
New SMB password:
Retype new SMB password:
Could not connect to machine 127.0.0.1: NT_STATUS_LOGON_FAILURE

not sure what that means except it should be able to connect to 127.0.0.1 as thats it's self
