When you reduce a screen shot, it likely uses some kind of resampling to
smoothe the image. That's great for more naturalistic color images -- it
reduces some of the crispness you get when you throw out pixels -- but
screen shots generally don't have the pixels to spare.

Your images look fine in print because you're probably not expecting to read
the screenshot in any detail. But onscreen it'll be incredibly obvious.

In short, the software isn't the culprit.
