If I want to make an image a real size (i.e. 3" * 4") what dpi should I use?

I need them to come out at that size when I feed the images into the engraver - it'll be 12 plaques laid out in a 1' square sheet of pre-polished brass, allowing 2mm for the width of the outlining tool.

I would probably assume you wouldn't want much more than 75 - 100 dpi for that, since it's hardly high resolution stuff..

I hear that so often and it hurts so much
a 3x4 image at 300 Dpi is 900x1200 pixels
a 3x4 image at 400 Dpi is 1200x1600 pixels
The Dpi is only relevent for printing it off at a higher quality.

I want it to look tidy at 3" * 4" when I feed it into the engraver.
In my experience telling an image to be a certain size in tatty shop has no bearing on the size it comes out.

with a "fit to page" setting or just a printer that isn;t as compatible as it should be.

that make it print at the size of the package.
(Print Options under File in most packages)
Chances are you'll need to do a few test prints, measuring the results with a ruler to be sure.
But 300Dpi should do you for that size.

I'd guess the more the better, depends what you printing it on too
anything over 300 should look decent enough?
shouldn't it?
