Cups write not in page_log

[Mario Scheel]

On my Debian SID system write cups not in page_log. I use hpijs with foomatic-filters.
in /etc/foomatic/filter.conf is set ps_accounting: 1
in the /var/log/cups/error_log is
"Inserting PostScript code for CUPS' page accounting "
from foomatic-rip script

I don't know where I can search. Can anyone help me?
