Thanks Juri.
What do you mean by 'accessible' - here I have only group execute  
permission, i.e.

ls -ld /var/spool/cups  gives
drwx--x--- 3 root lp 32768 May 14 11:37 /var/spool/cups

And what do you have in /etc/cups/cups-files.conf

Here I still have

# Default user and group for filters/backends/helper programs; this  
cannot be
# any user or group that resolves to ID 0 for security reasons...
#User lp
#Group lp

# Administrator user group, used to match @SYSTEM in cupsd.conf policy  
rules...
SystemGroup lpadmin


# User that is substituted for unauthenticated (remote) root accesses...
#RemoteRoot remroot

Many thanks again
Helmut.
