samba - Jul 2025 - Old Okis MF printer incompatible dialects

Hi,

I try to make my old printer send scans to the samba server. (because 
the linux scanner driver does not work yet)
This does not work. Samba 2:4.22.2-1 says "server does not support any 
of the listed dialects"

since the printer at least speaks LANMAN1 and 2, perhaps NT1 too
I believe samba simply does not understand the keywords sent for these 
dialects?
are they defined anywhere?

These are the dialects my printer announces:

 ?PC NETWORK PROGRAM 1.0
 ?MICROSOFT NETWORKS 3.0
 ?DOS LM1.2X002
 ?DOS LANMAN2.1
 ?windows for workgroups 3.1a
 ?NT LM 0.12

(fetched using wireshark)

Of course I tried different "client min protocol" values like LANMAN1 
LANMAN2, NT1

But this did not change anything.


thanks

Jan

Your printer is the client (which knows the protocols it uses) and your
Samba server is (well, obvious really) the server (which, at the moment
doesn't know the protocols that the client uses), so try 'server min
protocol = NT1' in the Samba servers smb.conf

I had to deal with some Oki multifunction printers in the past. I gave up
scanning to SMB. Scanning to FTP worked like a charm.
