graham,
first, it will be really hard to buy a non-color printer(exept laser printer). if you do go with a b&w printer, make sure the ground and background is in a light color. that prints out better.
second, check out some of my models at the 3d warehouse. http://sketchup.google.com/3dwarehouse/search?q=godsmack&styp=m
i have put several shooter's view in them.
good luck.
