samba - Oct 2002 - GetPrinter Level 2 does not get devmode

Hi all,

I have uploaded the printer drivers succesfully on RedHat Linux/ Samba
2.2.4 server. I can download and print without any problems. But when I do
Windows API call GetPrinter with PRINTER_INFO_2, the devmode in
printer_info is always null. My code looks like

     HANDLE hPrinter=NULL;
     PRINTER_DEFAULTS pDefaults;
     pDefaults.DesiredAccess = PRINTER_ACCESS_USE;
     pDefaults.pDatatype=NULL;
     pDefaults.pDevMode=NULL;
     BOOL b = OpenPrinter(cPrinterName,&hPrinter,&pDefaults);
     if (b)
     {
          LPBYTE printerInfo=NULL;
          DWORD dwNeeded;
          b = GetPrinter(hPrinter,2,NULL,NULL,&dwNeeded);
          printerInfo = (LPBYTE) new BYTE [dwNeeded];
          b = GetPrinter(hPrinter,2,printerInfo,dwNeeded,&dwNeeded);
          if(b)
          {
               PRINTER_INFO_2 * pInfo = (PRINTER_INFO_2 *)printerInfo;
               if(pInfo->pDevMode)
               {
                    if (DMPAPER_A4 == pInfo->pDevMode->dmPaperSize)
                         MessageBox("A4");
               else
                    MessageBox("LT");
               }
               else
                    MessageBox("Devmode is NUll");
          }
          else
               DWORD dwErr = GetLastError();
          delete printerInfo;
          printerInfo = NULL;
     }
     else
          MessageBox("Could not open printer");

     ClosePrinter(hPrinter);
     hPrinter = NULL;

I have checked the dump of nt_printers.tdb by tdbtool and the tdb looks ok.
I can see the devmode properly there. I repeat, I have no problems in
downloading and printing.

My requirement is I need to change some devmode setting of  a printer
depending on some parameters, and these should be visible when the driver
is downloaded to the clients. While working on this, I found that the
devmode returned by samba is null, and hence the driver reverts to the
default devmode values stored in the driver.

Thanks and regards,

Rohit.

Hi Jerry,
>Did you ever get the client to set it?  See the instructions in the
>Printing HOWTO one samba.org/docs
I uploaded the drivers from a Windows 2000 workstation, with the APW.
No errors were reported on the windows machine. This is supposed to set
the,
printer_info and devmode on the samba server, right? No other step from the
client
is needed to set these, as far as I know. Also, PRINTER_INFO_2
is NOT null. PRINTER_INFO_2->devmode is null, (just to clarify). I have
not checked the log while uploading, but while downloading I have and
I see a message "Returning NULL devicemode!" .

When I say I have checked the dump of nt_printers.tdb, I mean I have
visually verified. I know there
can be something wrong with the tdb, so I am going to check again.

Thanks and best regards,

Rohit.

Are you now something about specific data binary data named
"PrinterData", have length 560 bytes and saved into
ntprinters.tdb file.
This structure has any incompatibility between NT and 2K drivers.

Thanks

Hi Jerry,

I just went through Samba-HOWTO-Collection.pdf and am going to try
'tickling' the driver to save a devmode. Thanks for the pointer Jerry.

Also, I uploaded my drivers using the same process on a HP 4200 Print
Server Appliance which runs Samba too. I do not remember tickling anything
to set the devmode on the server , but I can still get devmode through my
program. I guess I need to verify this again.

regards,

Rohit.

Rohit,

Setting the devmode requires that the driver be executed (which
samba can't do).  Please read the Printing section regarding this in
http://samba.org/samba/docs/Samba-HOWTO-Collection.pdf

Yes.  I know exactly of the problem which you speak.  :-)

I did that a few weeks back, so I do not remember. I guess I used the PSA's
web ui probably.

native tools or through the PSA's web ui?  The Web UI initializes
the driver for you using some client side code.

Hi Jerry,

I followed the steps as outlined by Gregory in one of the posts to the
list.  That is


1. Define your printer as a share or in CUPS as needed.
2. Define PRINT$ share with only admin users having write access.
3. Restart Samba and make sure printer appears in the server Printers
folder
4. Right-click on the printer in question and choose Properties.
5. Respond "NO" to the "Install Driver now prompt"  -
Question:  Why
respond
"No" at this point? All docs say to do so without explanation.
6. Once in the driver dialog go to the Advanced Tab and click on "New
Driver"
7. Select your driver from wherever and make sure it copies to
\\Server\PRINT$\W32X86\...
8. Click on Apply to make sure dialog gets updated with printer-specific
configuration tabs.
9. On General tab, choose Printing Preferences - Basics and switch page
layouts between portrait and landscape clicking OK in between to update the
driver.  - I assume at this point the driver Devmode is being set, correct?
10.  The printer is now ready to install on Workstations.

I see a little bit of a different behaviour. After step 8, I do not see the
"Printing Preferences" button on the General Tab. I only see the
"Printing
Preferences" button if instead of "Apply" I hit "Ok"
and bring up the
printer properties again. (This I was able to reproduce with a HP LaserJet
8100 Series PCL 6 driver). (I am running Samba-2.2.4.)

Then if I do step 9, I see that the devmode for my printer is written under
HKEY_CURRENT_USER\Printers\DevModePerUser and
HKEY_CURRENT_USER\Printers\DevModes2 on the Windows machine from which I
was uploading the driver. If I run my program again to get the devmode, the
Windows API call gets the devmode from the local registry. If I delete
these registry values, it can only get the PRINTER_INFO_2 with null devmode
from the server.

Any pointers as to where the problem may lie would be very helpful.

Thanks and regards,

Rohit.

Ahh... The general tab is for the per user device mode.  You must do this
from the advanced tab to set it on the server.

Yeah.  This is the same thing.  Win2k does this.

Please test again with 2.2.6rc2.  There've been a lot of printing fixes
since 2.2.4.

Hmm.  All controls on the Advanced tab are greyed out, even for the
administrator connecting as root.  Is this related to being unable to delete
drivers from the ssrver using Server Properties?  This was mentioned as one
of the 2.2.6rc2 fixes.

Greg

Greg,

Do you have  the following defined in smb.conf ?

1. "write list = "  under [print$]
2, "admin users" and "printer admin" under global settings.

I think the advanced tab (or any other tab) will not be grayed out if these
are defined.

Hope this helps.

Rohit.
