I'm not particularly technical, but here is what I think is the explanation:
An SVGA (800x600 pixels) monitor has a fixed number of pixels in a given
area of the screen. If you capture that area in a screen shot, then try to
put the same image in a reduced area, you have fewer pixels to show the
original image. Naturally, you lose resolution on the screen. However, all
the original information still resides in the image; the screen just doesn't
have enough pixels to show it. A printer can show it because its resolution
is 600 dpi, much higher than the screen resolution. The printer can handle
the extra information in a reduced image.
Image editing software that has a "sharpen" feature can sharpen the image
somewhat. Try Microsoft Image Composer, PaintShop Pro, or some other similar
