[Samba] Samba + CUPS + Collation problems

I have been moving printers from lpd printing to samba print queues.   
Drive installs, point-n-print, and everything else is working well  
but I can't for the life of me figure out how to make print job collate.

I've been searching on how to correct this problem but have been  
unable to find anything.

My setup is
Samba 3.0.11 + 3.0.14a
Cups 1.1.20 + 1.1.23

In one test the queue is configured as a Raw queue and the native  
Windows driver is installed.  In test two the queue is configured  
with the foomatic driver for the printer and a generic PS driver is  
installed on the Windows side.  In both cases I get the Collate  
option in the Windows print dialog, I can check the box.  But the  
printer still outputs 2 copies of page 1 then 2 copies of page 2.  If  
I submit a job from another linux or Mac collation works so cups  
appears to be doing the right thing.  So I think this is a samba  
problem.

Samba conf (Important parts)
[global]
printing = cups
printer admin = @printAdmins
printcap cache time = 60

[printers]
         comment = All Printers
         path = /tmp
         create mask = 0700
         printable = Yes
         browseable = No

[print$]
         comment = Printer Drivers
         path = /var/lib/samba/printers
         guest ok = yes
         browsable = no
         read only = yes
         write list = @printAdmins
         force create mode = 0775
         force group = printAdmins
         force user = lp
         directory mask = 0775

Thanks for the help,
Derek
