If your application relies on a font being present it may be a better idea to include the font as a resource.
No, i want to know, what is the default font. Background: Between Jessi and Wheezy there must be a change in Raspbian in the default font (from liberationSans to freeSans).
Actual i have update my installscripts and install booth font-package.
fpreport cannot detect the font and use a predefined, not existing font :-( and on a LCL printout you see NOTHING. But there is another Bug ? prevent for a correct printout. I have fixed this with a 'hard' patch, but the issue with the font was only prevent by install all fonts on the systems. Regardless if they are Jessi or Wheezy (Buster) based.
