[Samba] share CUPS printer/scanner in Debian system with Windows computers in home network

[Seb]

Hi,

I've been trying to fix this for many months and cannot do it. I have a
printer (Samsung ML-1740) and a printer/scanner (Canon MP-150), both
installed in a Debian AMD64 system via CUPS. I have enabled sharing all
printers in this machine in CUPS, and can print to them fine from other
GNU/Linux systems in the network. However, I cannot even see this
computer from other Windows machines in the network, even though I have
the following in /etc/samba/smb.conf:

Can somebody suggest what may be wrong with this setup? Thanks.

On the samba server what does 'smbclient -L localhost' output?
Also, post the results of 'testparm -v'.

Looks like smbclient can see the printers fine.

Can you elaborate on what you mean by this?

Are you saying you can't see the list of printers or you can't even
connect to the samba server from a windows client?

The latter: I can't see the server at all from a Windows (XP or Vista)
client, yet it's certainly visible and its printers readily available to
any GNU/Linux systems in the network. Some people have reported that a
registry key
(HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\LMCompatibilityLevel)
needs to be set to 1. I did that, rebooted Windows, but nothing
changed. I also turned off the firewall in Windows to no avail. Quite
frustrating.

How are you trying to connect to the samba server from windows?

I tried (1) going to "Network", but I only see the local Windows machine
and the router, (2) map a network drive and provide "\\kolob\sluque",
but it tells me it can't access the server, and (3) adding a "network
printer" and choosing to browse for a printer, but the server isn't even
listed, and if I just give the address "\\kolob\ML-1740" it also tells
me that the server can't be accessed.

Ok, add 'log level=3' and remove 'syslog=0' in smb.conf. Go to
start->run->\\kolob and post the contents of
/var/log/samba/log.[windows-client-machine] after it errors out.

I did those changes, restarted samba, and tried to connect to \\kolob as
you described, but there's no /var/log/samba/log.magaly-pc file
produced, or other similar file with matching timestamp. The only
relevant changes in that directory are in /var/log/samba/log.nmbd, which
has these lines with that Windows client name (plus a few subsequent
lines that may be useful):

OK, I was able to connect to the Samba shares by using the IP address
rather than the computer name. I was asked to provide my user name and
password, and then the explorer window came up showing the printers and
the file shares. However, how could this Samba server be made visible
in the "Network" so that the printers alone can be added to those
Windows clients by any user (they don't need to be valid Unix/Samba
users in the server) by just doing "add network printer"? Why can't the
"add network printer" not be able to detect the public printers by just
browsing? Thanks so much for the guidance!
