Thank you. I have tried version 1.7.2 - same result. But it is solved: the .pkl-file is wrong.
I have taken a new set of dejavo*.ttf files from http://freefr.dl.sourceforge.net/project/dejavu/dejavu/2.35/dejavu-fonts-ttf-2.35.zip . Then I have unziped and copied these files into contrib/fpdf/font fpdf creates new .pkl after the first usage. Don't forget to make www-data the owner of the font directory: chown -R www-data:www-data font Maybe a short description of these steps in the web2py book could help others to use fpdf.
