[SOLVED] Cannot print from Windows 7 clients

I am stuck getting network printing to work with an up-to-date zentyal server:

I setup the CUPS server using the CUPS web admin interface: under Administration > Server, I check "Share printers connected to this system" and "Save debugging information for troubleshooting".  (I also tried checking and unchecking "Share printers connected to this system > Allow printing from the Internet", "Share printers connected to this system > Protocol > LDAP" and "Use Kerberos authentication", to no avail.)

I add a printer.  While setting the default options for the printer, I hit an error--"unable to set options: broken pipe"--but the configuration appears to succeed.  The printer is listed as

Code: [Select]

Samsung_ML-1450 (Idle, Accepting Jobs, Shared, Server Default)
Description: Samsung ML-1450
Location: Laundry room
Driver: Samsung ML-1450 Foomatic/pxlmono (recommended) (grayscale, 2-sided printing)
Connection: parallel:/dev/lp0
Defaults: job-sheets=none, none media=na_letter_8.5x11in sides=one-sided

and printing a test page from CUPS works as expected.

I see the printer under zentyal's admin interface and allow guest access.  The corresponding /etc/samba/smb.conf sections appear as

Code: [Select]

[print$]
    comment = Point and Print Printer Drivers
    path = /opt/samba4/var/print
    read only = No

[printers]
    comment = All Printers
    path = /opt/samba4/var/spool
    browseable = Yes
    read only = No
    printable = Yes

I add the network printer from a Windows 7 client.  Windows finds the printer but no driver, so I pick the matching driver from the Windows-provided list.  When I try to print a test page from Windows, nothing happens on the client--no error messages--but nothing is printed.  In the CUPS error_log, I see

Any help here would be greatly appreciated.  I am no printing expert--for the last 10 years or so, CUPS has "just worked"--and am not sure what else to try.

check permissions for /opt/samba4/var/spool and /opt/samba4/var/print
I thing they must be 1777..

Thanks for the tip, mamra.  I don't see the directories you identify--the closest I that I could find are listed below:

Code: [Select]

/var/spool/samba is 1777, as you recommend.

I wonder if there is an authentication issue with CUPS?  This line from the CUPS logs concerns me:

D [24/Feb/2013:09:09:23 -0500] cupsdAuthorize: No authentication data provided.

Might this be the source of the printing problem?

Please create the directories as they are mentioned in smb.conf

Thanks, mamra.  That did the trick.
