[Samba] hp officejet 9130 and samba

[kurt weiss]

we're using an hp officejet 9130 (all in one printer/scanner), wich has 
the possibility to store scans on a network share (smb).

path, username and password are checked on a workstation and are ok.
the printer has full access to the network.

unfortunally samba denies access:
<snip filename="log.smbd">
[2005/10/06 14:46:22, 0] smbd/negprot.c:reply_negprot(557)
   No protocol supported !
</snip>

in smb.conf we'd defined the max protocol as LANMAN2
on the printer we've tested following options:
LM/NTLM
NTLM
NTLM2
allways the same message.

samba version: 3.0.11

can somebody help / has somebody experiences?

thx in adv
kurt
