You cannot get that information from the painter itself (a print
composition can be printed into QImage, pdf, QPrinter, etc...).
The safest guess is probably to look at the QgsRenderContext. If
the parameter 'scaleFactor' is very close to 1.0, it is most
likely the rendering comes from a print composition.<br clear="none">
