Thanks. However, this did not change anything:

before:
drwxrwxrwt 2 root lpadmin 4,0K Jan 26  2015 ANONYMOUS
drwxr-x--x 2 root lpadmin 4,0K Mai  6 13:36 SPOOL
felix at bitburger:/var/spool/cups-pdf$

after:
drwxrwxrwt 2 root lpadmin 4,0K Jan 26  2015 ANONYMOUS
drwxr-x--x 2 root lpadmin 4,0K Mai  6 13:36 SPOOL

So I guess anonymous access is already enabled.

Does anyone have an idea why the PDF does not arrive in ~/PDF, there is
no error the error_log and the access_log is different from a successful
PDF printout (see above)?

Many Thanks and Best Regards,
