[Samba] Spool queue issue winxp and samba-3.0.x

[Samba List Unetix]

Hai,

Lately I am encountering a weird issue with spool queue under winxp and
samba+cups.
It seems winxp puts all the information of printjobs spooled to a given
printer exported with samba in its local printer spool queue of that printer 
(allso of other users in the domain) and never marks them as 
done/expired . After a certain amount of time there are so many jobs in the 
queue the workstation  refuses to print to that printer. It is impossible to
remove the printjobs or otherwise manipulate the local spoolqueue.
The latest site where I maintain a samba file/print server exhibited this 
issue after I upgraded from samba-3.0.4 to samba-3.0.10 with following 
config :
smb.conf :
[global]
       ........
        load printers = yes
#       printing = bsd
        printing = cups
        printcap name = cups
 
[print$]
 comment = Printer Driver Download Area
 path = /usr/local/shares/drivers
 browseable = yes
 guest ok = yes
 read only = yes
 write list = @sys, root, @wheel

[printers]
  comment = All Printers
  path = /tmp
  browseable = No
  printable = Yes
  guest ok = Yes
  read only = Yes
  print command = lpr -P%p %s

Any pointers are appreciated
TIA
