samba - Aug 2008 - Samba with cups. when cups shutingdown client view nothing

hi list,

I have installed a samba with cups for share all printers on network.
When i stop the cups server  i was thinking that the windows client veiw
their print device as on error however the client view nothing. All printers
are allways shared?
when i send a print job on a queue the client says nothing on error and the
jobs is not stored in /var/spool/samba and of course it's not printed
When i do refresh from Windows clients i always see the printers.

Version: OS Fedora core 3
samba 3.0.21b-2

My configuration:

; Directive de configuraiton des impressions
   printcap cache time = 10
   printcap name = cups
   load printers = yes
   printing = cups
   printer admin = "@MERCATOR-OCEAN\admins du domaine"
   cups options = raw

   security = ADS
   local master = no
   os level = 10
   domain master = no
   preferred master = no
   domain logons = no

Everything works fine else

In the log file i see

  Printcap cache time expired.
