Question

Unable to export Windows drivers from CUPS to Samba on FreeBSD 7.2 server

Asked by: breakingthelaw

Hi,

A few days ago I installed Samba 3.3.8  (file server + PDC)  and print server (CUPS 1.3.10) on a FreeBSD 7.2 machine.
File service and PDC works ok.
I can print from CUPS web inteface directly.
I successfully added the printer to one of my Windows workstations but I had to supply the driver manually.
At the moment I wish to create a printer driver share but the cupsaddsmb refuses to:

myserver# cupsaddsmb -U root -a -v
cupsaddsmb: No PPD file for printer "hplj6l" - Missing double quote on line 224!

Now, hplj6l is how I named my HP LaserJet 6L printer in CUPS. I installed it using a ppd file from linuxprinting.org (HP-LaserJet_6L-lj4dith.ppd). CUPS also seems to have put a file named hplj6l.ppd in /usr/local/etc/cups/ppd/hplj6l.ppd. I tried to run cupstestppd against the two files but they pass ok.
Tried to add the two files and hplj6p_4.ppd (a file from Windows driver cab) to /usr/local/share/cups/model, but no effect.

I made sure I have the following lines in /usr/local/etc/smb.conf (as suggested in cupsaddsmb man page):
[globals]
(...)
load printers = yes
printing = cups
printcap name = cups

[printers]
         comment = All Printers
         path = /var/spool/samba
         guest ok = Yes
         printable = Yes
         browseable = Yes
         public = Yes

 [print$]
         comment = Printer Drivers
         path = /usr/local/share/cups/drivers
         write list = root, alnis
         guest ok = Yes
         browseable = Yes
         write list = root
         read only = yes

And I have these files in /usr/local/share/cups/drivers:

cups6.inf                       hplj__31.ppd
cups6.ini                       hpljps1.ini
cupsps6.dll                     hpprn02.dll
cupsui6.dll                     lj456ps.inf
hp-laserjet_6l-lj4dith.ppd      pcl4res.dll
hplj4mv1.ppd                    pcl5eres.dll
hplj5m_4.ppd                    pcl5ures.dll
hplj5p_1.ppd                    pcleures.dll
hplj5si1.ppd                    pclxl.dll
hplj5sim.ppd                    ps5ui.dll
hplj6p_4.ppd                    pscript.hlp
hplj_3d1.ppd                    pscript.ntf
hplj_3p1.ppd                    pscript5.dll

What causes the strange error or how can I work around it?

If you open the PPD file, what is on it's line 224?
Appearantly a " is expected on that line, it would indicate a problem with the ppd, or with the
code in 1.3.10 in cups adminutils.c source.

 

by: breakingthelawPosted on 2009-11-09 at 05:31:15ID: 25775703

The content of line 224 in HP-LaserJet_6L-lj4dith.ppd :

224 *FoomaticRIPOption Copies: int JCL A

 

by: nociPosted on 2009-11-09 at 08:24:33ID: 25777335

Ok I found the ppd file. First about cupssmbadd...:
All lines between "*JCLOpenUI" and "*JCLCloseUI "
should either be an ("*Orderdependency", starting with "*End", "*Default" ) OR contain a : and a "   type of line.
After a " a multiline copy is made until the closing ".

Now,
a Postscript job is expected, and a Postscript job DOESN't contain JCL   (@PCL options!!).

So you effectively need to remove the JCLOpenUI .. JCPCloseUI lines to be able to use this as Postscript jobs file.


(BTW, JCL ui options cause lines like then next to be inserted (f.e. when selecting 7 Copies.) at the top of a job.

@PJL SET COPIES=7

Cups postscript cannot handle this correctly.
Did you also check the PPD's files from HPLIP (HP's linux driver project)?   http://hplip.sf.net

I noticed that there's difference between the permissions CUPS itself has made for its drivers in

/usr/local/share/cups/drivers and the Win drivers I copied there. So I changed the permissions to

cups:wheel 644, and now cupsaddsmb executes ok, at last. The errorr message about double quotes was misleading.

But there's another issue I can't still figure out: I can only add that printer on Win workstations when

I log in there with local administrator's priviledges. If not, an error message pops up:

"A policy is in effect on your computer which prevents you from connecting to this print queue. Please

contact your system administrator."

I set /var/spool/samba permissions to 777 but this didn't change anything.

Doesn't that have to do with windows group policies?
(Probably a default, that needs to be set to allow?).

 

by: breakingthelawPosted on 2009-11-10 at 01:20:54ID: 25783667

By default, no restrictions are set for regular users to add shared network printers. Those printers then appear only in the users profile. I have had some other installations with printers shared on samba/cups, and this has never been an issue. AFAIK, iIt's also never restricted in an Active Directory domain by default. So, to edit each computer's local group policy would be quite an  inconvenient workaround.

From http://support.microsoft.com/?kbid=319939:

"By default, this policy setting is not configured. If you do not configure this policy setting, users cannot download Point and Print drivers from computers that are not in their Active Directory forest."

But my print server is in the domain, only it's not an Active Directory domain. But ok, editting local GP "Point and Print Restriction" solves the issue.
