Screen resolution is 72 pixels per inch. But print resolution is determined by your printer, not your monitor. So if you have an image thats, say 144 pixels high and your printer resolution is 100dpi, itll print out at 1.44 inches high. Now, not to complicate things, but if you take the image and export it into a program such as Pagemaker or QuarkXpress, then the resolution will be determined by what sizing you give the image. Taking, again, the example of the 144-pixel image above, if you import it into Pagemaker into a picture window thats 8" high, itll indeed print at 8" high but with a lot of fuzziness since there isnt much image information to work with.
