Hi Andrew,

Printing from paper space always assumes (by design) a scale of 1: 1 - this is precisely why paper space exists. You create page setup with paper size you need to be printed, then create viewports in the Layout with desired scale, then print with "Print Layout" (not "Window") option activated. So in Paper space output scale determined by the viewport scale.

Can you share the drawing in question? I'll look at it.
