The screen has special characteristics, weaknesses and abilities, and you should take them into account.
Textured backgrounds work well on screen, but are only practical with specialized printing on paper.
A paper page has more area and higher resolution than most screens, so paper lends itself more to mixing overview and detail on the same page. Screens are typically landscape in orientation, encouraging the use of sidebars for information that might be more likely in banners on paper. Use designs that take into account measures that vary with window size, and that can work on 640x480 pixel windows. Following a reference to an arbitrary page that is not the next or previous one is very cumbersome with paper, but very natural with the screen. Links can be an integral part of screen designs.
