The edit screen screenshots print quite well in black & white if you invert them first. The same should work with the test view if you set the sun low (this makes the background dark, which comes out very light when inverted).
I recommend the shareware program "Graphics Workshop". It lets you make preview "thumbnails" for all the screenshots, select the ones you wish to print and batch "Reverse" = invert them, batch grayscale (in "Effects" ) and batch print them, so it's no problem to do this with 20 screenshots at once
You can get it here.
