Spool filename. ( What is the problem? )

[Daniel William Schultz]

Here is my printer config:

    printing = lprng
    load printers = yes
    use client driver = yes
    printer admin = @edutec, root
    printcap name = /etc/printcap
    print command = lpr -U%U@%M -r -P%p -J'%J' %s
    lpq command = lpq -P%p
    lprm command = lprm -U%U@%M -P%p %j
    lppause command = /usr/sbin/lpc -U%U@%M hold %p %j
    lpresume command =/usr/sbin/lpc -U%U@%M release %p %j
    queuepause command = /usr/sbin/lpc -U%U@%M -P%p stop
    queueresume command = /usr/sbin/lpc -U%U@%M -P%p start


On the print command I have put the variable %J , to get the original 
filename, but it's empty...
On samba 2.2.1a it worked, but now in 2.2.2 seems to not work.
This variable get deprecated ?
Please, any help is welcome, my boss is asking me all the time about 
this, and I don't want to downgrade to 2.2.1a to have oplock problems 
again :)

Thanks in advance,

Daniel.
