Hi Michael,
Yes, please file a bug if something changed here.
Would -[NSGraphicsContext isDrawingToScreen] work for you? It really
has more to do with whether the destination context is pixel-based
than with whether it's the screen.
"A return value of NO may mean that the drawing destination is a
printer, but the destination may also be a PDF or EPS file."
This will not help if your goal is to distinguish between printing to
a printer and printing to a PDF.
