When printing a simple rectangle sized 200 mm long / 100 mm wide on my Brother DCP-J152W, scale set to 1:1, the result differs per printing mode.
Both set to Extends, printing as vector results in the correct dimensions, however printing as raster results in 200 mm long (horizontal) and only slightly less than 99 mm wide (vertical). Both landscape prints.
So the vertical scaling is off by more than 1% in Raster mode, while a vector print is spot on! Very odd.
I also saw the preview do a little jump when I swapped between the two modes.
