Hi Ville, thank you for contributing this patch, I will push and build it. I am going to send this patch to upstream too, if you haven't done it yet. Can I do that for you?
I would have submitted this (only) upstream already, but upstream's cups-genppdupdate is completely different from the one in this package (written in Perl, not Python): https://sourceforge.net/p/gimp-print/source/ci/master/tree/src/cups/cups-genppdupdate.in
Python3.6 is already in Fedora 26, switching to f26.
