[Lazarus] fpreport: Rendering Report to Printer did not work on RasPi (arm-linux)

[Andreas Frieß]

Who is the renderer for printer (gtk2/linux/arm) used in fpreport ? The
printer itself is cupsprinters (found in OSPrinters). But i have not
the glue which renderer is used, because the output in cupsprinters is
postscript.

Have somebody a hint for the used renderer for me? Or should i file a
bug ?

With qtprinters it is correct rendered.
