Samba+Cups - no entries in page_log

[Karsten Dello]

good evening,

if i print to our cups-server from a winxp-machine via the samba-server on the same machine  the job is done well.
i can also see the corresponding entry in http://...:631/jobs?which_jobs=completed

but no entry is made into /var/log/cups/page_log,
which i need for some kind of "basic" accounting.

on the client-side we use
the cups-printer-driver (rc3),
on the server-side we use cups 1.1.20 and samba 3.0.7.

any help would be appreciated,
