Bug Description

SRU justification :

It is currently impossible for a USB connected printer shared on Ubuntu 12.04 to be added to a Windows XP / 7 using the "Discover printer" functionality

Impact :

Users cannot use such printers shared by Ubuntu Precise

Fix :

Samba bug #8554 provides a fix for this issue. The fix is part of the Quantal version of Samba (3.6.6)

Test Case : See comment #75 for a detailed description of how to reproduce the bug and confirm the fix

Regression : None expected as the fix is already part of the version used in Quantal

Description of the problem :

Since installing 12.04 I can no longer connect my windows XP clients to my laser printers on the Ubuntu system using samba.
It works on 11.10 using the exact same smb.conf file.
I can see the printers from the windows clients, I can select it, I install the drivers locally from the windows pc. When I click next I get the message "Windows cannot connect to the printer. Either the printer name was typed incorrectly or the specified printer has lost its connection to the sever".

This is a deal breaker for me.

The same for me. I'm trying to connect from Windows (XP and 7) to a shared printer on Ubuntu Server 12.04. And both on WinXP and Win7 get the same error as others in this thread after drivers installation (in Russian: "Windows не удается подключиться к принтеру. Введено неправильное имя принтера или указанный принтер утерял подключение к серверу").
At the same time, I can add a network printer, using "http://<hostname>:631/printers/<printername>", but it is not convenient for the users.

I am rather new to Ubuntu. Is it possible to uninstall this version of SAMBA and revert back to an earlier version (Which worked fine) until this bug is fixed? I did the same thing, upgrade from 11.10 to 12.04 and now I cannot use my Linux shared printers on my network. (PCs are using both Vista and XP OS). My configuration and applications are basicly what came with the original Ubuntu install download.

This bug is somewhat a deal breaker for 12.04 for me. A search on Google will likely show up an array of deal break bugs for Samba 3.6.x. I've been hoping for a fix to come over the last few weeks, but on looking at the upstream release notes, there doesn't seem to be a fix in the pipeline for this, although the most recent update to samba has many, many bug and security fixes.

Perhaps Andrew Tridgell is busy fire fighting at the moment with the 3.6 series. I understand substantial sections have been re-written and obviously not yet mature code.

Perhaps distributions need to do their own code quality control, and perhaps make choices whether to include the latest versions if too buggy.

I'd suggest the previous 3.5 series of Samba should be included in 12.04 repositories, and available by default at least until samba 3.6 is more mature.

I wish I had the time, knowledge and resources to help Andrew Tridgell in his programming efforts on Samba.

If someone needs a network for attempting to fix this, I offer mine if it will help. 1 Ubuntu 12.04 Server, 2 Ubuntu 12.04 clients, 2 windows 7 clients.

Posible solución:

Comando a usar: rpcclient

Se tiene que establecer el nombre de la impresora

Teclear en la terminal del servidor el siguiente comando sin las comillas:
“rpcclient localhost”

les pedirá la clave del usuario samba que administra las impresoras,

pueden verificar el nombre de la impresora con el comando, sin las comillas “enumprinters 5”

Ejemplo si el nombre de la impresora compartida es PDF2

luego de este paso cambian el nombre de la impresora con el comando, sin las comillas
“setprintername PDF2 PDF2”

ir a un maquina cliente, instalar la impresor.


In Ingles

Possible solution:

Command to use: rpcclient

You have to set the printer name

Type in the terminal server the following command without quotes:
"rpcclient localhost"

Asked the samba user's password that manages printers,

Can verify the name of the printer with the command, without the quotes "enumprinters 5"

Example if the name of the shared printer is PDF2

After this step change the name of the printer with the command, without quotes
"setprintername PDF2 PDF2"

Go to a client machine, install the printer.

fix in comment # 21 worked for me

James Brown (ta2-0) wrote :

#21 worked for me too, but really needs a better explanation.

rpcclient needs to be run as superuser - it did not work for me until I changed user to root (su root)

i did not try it, but I think "sudo rpcclient" should work as well if you have enabled root directly.

typing "enumprinters 5" resulted in one listing for each of the printers in my system, but the result for each priner was


"enumprinters" (without the "5") yielded this with the correct name for each printer:

        description:[\\LOCALHOST\HP-LaserJet-1100,,HP LaserJet 1100]
        comment:[HP LaserJet 1100]

typing "setprintername HP-LaserJet-1100 HP-LaserJet-1100" resulte din a success message.

typing "enumprinters 5" now lists the printer with the correct name. and I can connect normally from the Windows clients.

I do not know what the "5" means, but apparantly the upgrade did something to zero out the existing settings.

David (orlando-dad) wrote :

Bad Spanish

Disculpen por la mala explicacion en el comment #21.

Bueno, en mi configuración de samba el grupo lpadmin es administrador de impresoras, mi usuario pertenece al grupo lpadmin, por eso funciono para mi sin ser usuario root (opcional agregar "printer admin = @lpadmin" en smb.conf sin las comillas), el usuario root es siempre por defecto administrador de impresoras.

Para una mejor explicacion del comando rpcclient y su uso podemos acudir siempre al man del comando.

Tomado del manual :

"enumprinters [level]
           Execute an EnumPrinters() call. This lists the various installed and share printers. Refer to the MS Platform SDK documentation for more details of the various flags and calling options. Currently supported info levels are 1, 2 and 5."

 "setprintername <printername> <newprintername>
           Set printer name"

Bad English

Sorry for the bad explanation in comment #21

Well, in my samba configuration the group lpadmin is printer manager, my lpadmin user belongs to, so it worked for me without being root user (optional add "printer admin = @lpadmin" in smb.conf without the quotes), the root user is always default printer manager.

For a better explanation of the rpcclient command and its use can always consult the man command.

Taken from the manual:

"enumprinters [level]
           Execute an EnumPrinters() call. This lists the various installed and share printers. Refer to the MS Platform SDK documentation for more details of the various flags and calling options. Currently supported info levels are 1, 2 and 5."

 "setprintername <printername> <newprintername>
           Set printer name"

Please also see Bug 990388 which has similar symptons (cannot print from windows to linux after upgrade from 11.10 to 12.04).

The resolution there is about allowing windows client drivers, see comment #5.

Apologies if this isn't the right way to relate bugs, I'm new to launchpad.

Whilst attempting the fix outlined in #21 / #25 / #26 I found this:

root@exabytes:/home/james# rpcclient localhost
Unknown parameter encountered: "lpq"
Ignoring unknown parameter "lpq"
Enter root's password:
rpcclient $> enumprinters

Am I correct in thinking the printer has somehow lost its name? "name:[\\LOCALHOST\]"

Attempting to change the name regardless results in the error:

rpcclient $> setprintername HP_C4480 HP_C4480

The results are the same for both users 'root' and 'james' (a member of lpadmin).

smb.conf contains...
   printer admin = @lpadmin, james

Is anyone able to shed some light on what's happening here? Many thanks.

I can confirm libpam-smbpass is already installed and services were restarted after making the change. The results are the same. Full system also rebooted for good measure.

There seems to be something iffy with the permissions: The rpcclient output for "enumprivs" is identical for both a member and non-member of the lpadmin group.

I'm sure your fix will solve my problem, just as soon as I get my permissions in check. Looks like I have a bit of reading to do!

I can confirm "james" is a member of lpadmin and am still getting the "WERR_ACCESS_DENIED" message, despite following your suggestions.

If you are interested, I have placed some rpcclient output and the active content of smb.comf in the pastebin:


David (orlando-dad) wrote :

Hi James,
I check your configuration file,
you have two [global] section delete the second, only the [global]

You must replace the section [printers] with the following:

    comment = All Printers
    browseable = yes
    path = /var/spool/samba
    printable = yes
    guest ok = yes
    create mask = 0700
    printer admin = @lpadmin
    valid users = james

enumprivs: only lists the existing privileges, does not list the current user's privileges, so I think.

try it and comment.

jmsfnch (jamesfinch) wrote :

Hi David,

It's looking good :-)

I made the recommended changes and at first the result was the same. I had also to comment out "read only = yes" from the "[print$]" section - doing so allowed me to successfully set the printer name.

My XP test box can now connect to the renamed printer.

Thanks very much for your help. James.

James Page (james-page) wrote :

Reviewing all of the comments on this bug report to-date its looks like there are probably two issues:

1) A potential race condition between cups and samba which means that samba is unable to lookup the list of printers on startup.

This is indicated by the following log messages in /var/log/samba/log.smbd:

[2012/04/02 13:17:15.089590, 0] printing/print_cups.c:110(cups_connect)
  Unable to connect to CUPS server localhost:631 - Connection refused
[2012/04/02 13:17:15.090587, 0] printing/print_cups.c:487(cups_async_callback)
  failed to retrieve printer list: NT_STATUS_UNSUCCESSFUL

I think we can put in a conditional wait in the upstart configuration file for smbd to ensure that the cups daemon is in a running state before samba starts.

2) A change in behaviour which subsequently causes printing to fail with authentication issues (thats a premise - remains unproven IMHO).

I've tried to reproduce this issue using a Windows XP Client -> Ubuntu 12.10 Server; however I was able to print successfully so we need to dig into this a bit further.

It would be really helpful if the original bug report or anyone still seeing issues could increase the log verbosity by adding:

   log level = 3

to /etc/samba/smb.conf; any additional log information post restart for samba for both the server processes and the client connections would be really helpful.

This second issue might be related to bug 990388 - but its hard to tell at this point in time.

Please could you repeat with a log level of 10 - if the log looks exactly the same as in the upstream bug I think we can confirm the issue sufficiently.

Since the last samba updates to precise the two workarounds (installing 3.5.6 deb package or using samba 4RC1 from the software centre) that I mentioned above are no longer effective; 356 will not install, and 4RC1 will not start.

I am able to share the brother printer on p5q using a uri of ipp://

But the computers running ubuntu 12.04 or variant cannot see the others using samba.
And to answer the above poster, the ubuntu based machines cannot see the HP printer on the winxp host.

I'm interested in helping to troubleshoot, but don't know how.

Hi to whom it may concern,

At the top of this posting, it states that this bug affects 40 people but judging by the number of google references and comments on the Ubuntu Forums, it affects a great deal than 40. I am referring to the bug where one seems to be unable, to set up a printer attached to a 12.04 server. You see the following error message.

"Windows cannot connect to the printer. Either the printer name was typed incorrectly or the specified printer has lost its connection to the server".

I had this problem on a new server that I had created using Xubuntu 12.04 and which was attached to various windows PCs. Most of these, are running XP Pro. I do not have the problem on a Xubuntu 10.04 server which is attached to the same XP Pro PCs.

The Printer would work locally from the server using USB and another printer of the same type was setup directly on the LAN. This lead, in-fact, to one additional problem. See later.

I eventually managed eventually to get it to work by setting up from the Windows PC to my server using the semi manual approach, of using the syntax where is the server address.

Whereas the original printer which was on the Lan, had been set -up under windows as a port name of


And this was automatically found on the Windows PC's Whereas on the 12.04 Xubuntu server it would not find it so it had to set-up manually as

ipp:// ie it's address on the LAN and that seems to be CUPS error.
This printer uses a name of Brother-HL-2270DW_series

NB the slight difference in the name between the DW and series one is an underscore and the other is a hyphen. This was the cause of a few unsuccessful attempts of getting it to work!!!

CUPS was setting up slightly different IDs as seen on the jobs page (CUPS) and show all jobs..

Hi all,

I'm having trubles adding shared printer from Xp clients.
I got the message "Windows cannot connect to the printer. Either the printer name was typed incorrectly or the specified printer has lost its connection to the sever".
I tried solution @ #21 but when typing enumprinters i get


as @ #28.

Why there is no printer name? How should i set it?

alfalfa, as quick solution, try adding printer using URL (there should be an option for that in "Add pritner" dialog box. URL of printer page is the same it has in CUPS webinterface (most likely it looks like http://printserver.addr:631/printers/Printer_Name ).
It worked for me.

We all know there are workarounds for this and what surprises me more s that after 8 months NO FIX! I just took my install of ubuntu 12.04 to the latest samba packages from Raring and the problem is still there . I was already running CUPS 1.61. What I did notice is something I did not see before when I ran

cupsaddsmb -H localhost -U root -h localhost -a -v

It returned an error about an invalid printer .

So then I run
rpcclient -U root localhost -c enumdrivers
rpcclient -U root localhost -c enumprinters

And only one driver and two printers (one is PDF) . The PDF printer nor driver are anywhere t be fund but the driver for the PDF printer was made available to windows! What gets even weirder is that I cn print to the PDF printer via Samba and a postscript driver! Considering that samba does not even see it as installed thats odd

Is this a samba bug or cups bug?

Unlike previously, the "name:[...]" value is now complete with server & printer name. This is confirmed by setting up a printer on Windows XP as well.

It would be greatly appreciated if someone affected by this bug could test on an up-to-date system (12.04 preferably) to try to reproduce the bug. My feeling is that the source of the problem was not samba and got recently updated.

But after two complete days of thorough testing, I am not able to reproduce the bug anymore !

Regarding the upstream samba bug (#8769), it is not related to this issue and should be removed as a reference.

I just did an apt-get update, and can confirm I am on the latest samba/cups with 12.04.1. I used the 64bit server install CD.

This bug still exists.
This is bull. I could be developing open source, instead, I'm trying to get samba to print.

Okay, after numerous retries (as in at least 20 virtual machines), I think I have identified a systematic way to reproduce the problem.

Test environment
1 virtual machine running Ubuntu 12.04 Precise with USB connected printer [1]
1 virtual machine running Windows XP

1) add the samba package
 $ sudo apt-get install sambe

2) Modify the /etc/samba/smb.conf
 workgroup = MSHOME
uncomment the two following lines :

   printing = cups
   printcap name = cups

3) Go in the "Printers" administration tool and enable sharing
 Server->Settings and enable the checkbox on :
 "Publish shared printers connected to this system"

4) In a terminal, type :
 $ sudo lpstat -a
Deskjet-2510-series accepting requests since Mon Feb 11 11:27:46 2013
 $ sudo rpcclient localhost -Nc enumprinters
No Printers returned.

This confirm that the printer exists but has not been picked up by Samba.


The sequence of event is required otherwise the bug will not occur (which is why I was no longer able to reproduce the problem). The upstream samba bug #8554 had the explanation ( :

"... where a newly created CUPS printer would be loaded into smbd with a
broken "printername" of '//LOCALHOST/', i.e. missing the actual share name
(empty in the outgoing spoolss_GetPrinter structure after the initial
OpenPrinterEx rpc command). Maybe this is also the case in 3.6.0. Without
Björns patch this happened whenever the first connect to the new printer share
would be initiated by a non-privileged user logged on to a Windows client (XP
or 7).

The "whenever the first connect to the new printer share would be initiated by a non-privileged user logged on to a Windows client" is important as, if smbd is restarted BEFORE this connection happens, the printer name will come up correctly !

5) Try to add the printer from Windows XP using the dialog until the "Search printer" shows the Precise VM in MSHOME workgroup by double-clicking on the Precise hostname. Nothing should happen.

6) in the terminal type :
 $ sudo restart smbd

7) Double-click on the Precise hostname. The printer should appear. Double-click on the printer. This double-click should trigger the bug and you should see only \\{precise hostname}\ in the Printer field. To confirm that do the following in the terminal :

 $ rpcclient localhost -Nc enumprinters
        description:[\\LOCALHOST\,,HP Deskjet 2510 series]
        comment:[HP Deskjet 2510 series]

The "name" field show that the printer name is missing and only the hostname appear.

Using the following steps, I am able to reproduce the bug systematically.

So from that, I did apply the patch from Samba bug#8554 to the precise-update version of the samba package and it does indeed fixes the issue, using the above method of reproducing the bug.

The one issue to be aware of is that the old entry for the failing printer will remain in Samba's registry.tbd database. In order to reset its value, the printer should be removed from CUPS and recreated, otherwise the previous entry will remain and the printer detection will continue to fail due to the ...

Any news on the release of this fix for precise? I'm preparing to set up servers for windows networks, and I need to know what workaround I have to use. 3.6.6 as originally released is not going to go on these servers.

I've made Ubuntu my distro of choice, but this was reported almost a YEAR ago, and Precise is supposed to be a LTS. It really makes one think about CentOS.

If this was a minor bug, it's one thing, but this isn't a minor bug, IMO.

While I would advise against it, you can pickup the packaging files and build yourself a PPA (clicking on the arrow symbol beside the package name will expose the packaging files) until it gets uploaded. But it now only a matter of time until it becomes available in -proposed for testing.

Louis Bouchard (louis) wrote :

One thing to be aware of that I noticed while testing.

Even with the patch applied, existing printers will not get updated entries in the samba registry. I have found no other way than deleting the registry file completely to get new entries created. I had to do the following :

 $ sudo rm -f /var/lib/samba/registry.tdb
 $ sudo rm -f /var/cache/samba/printing/*
 $ sudo restart smbd
 $ sudo restart nmbd

Maybe there is a smarter way of cleaning it up but I haven't found it

Hi ,

I guess I have a problem connected to this thread:
I installed latest image ubuntu-13.04-desktop-i386.iso,
on the laptop, I have HP printer connected to it and
work well, but when I share it I can see it and connect to
it from windows machine but not send a test page print.
