1.2.7: browsing is OFF, cups but still browsing

[ekkard gerlach]

lpstat -t  shows printer queues that are not in local 
/etc/cups/cupsd.conf  even though browsing is switched off:

cat /etc/cups/cupsd.conf
# Show troubleshooting information in error_log.
LogLevel debug
SystemGroup sys root
# Allow remote access
Port 631
Listen /var/run/cups/cups.sock
# Disable printer sharing and shared printers.
Browsing Off
DefaultAuthType Basic
<Location />
[...]

Why?

thx
