[Samba] samba no deleting spool files

[Pablo Marques]

I have samba version  2.2.5 with printing patches.
printpro 4.2.2 = cups version  1.1.14 (I think)

The files queued in /var/spool/samba don't ever get deleted!!
They are deleted after they are printed by cups in the cups spool
directory.
Why is samba not deleting the files?
Do I need to specify a pint command?

Thanks

This is my samba config:
