http://hplipopensource.com/node/372 says:

Extension modules are missing from the current Python path "/usr/lib/python/dist-packages".
This happens when HPLIP is installed using one python version and you are running HPLIP using another python version.
For example, HPLIP was installed using python2.x and running the tools using python3.x

locate cupsext.so
/usr/lib/python3.5/site-packages/cupsext.so

ls -al /usr/bin/python
lrwxrwxrwx 1 root root 9 3. Jul 23:49 /usr/bin/python -> python2.7

switch active python version
rm /usr/bin/python
ln -s /usr/bin/python3.5 /usr/bin/python

set debug in cups.conf
vi /etc/cups/cupsd.conf
LogLevel debug

systemctl restart cups-browsed.service

/usr/lib/cups/filter/hpps with errors in Ident (^I).
Changed the ident, maybe its wrong, but printer works.

vi /usr/lib/cups/filter/hpps

   193          szKeyInitials = ['HPFIDigit', 'HPSEDigit', 'HPTHDigit', 'HPFTDigit']                                 $

Thank you for your quick response!
The patched hplip works like expected.
But the link to python3 must be set by hand.
ln -s /usr/bin/python3.5 /usr/bin/python
