latex - Beamer printout

documentclass[handout]{beamer}

achieves what you want. I also write

mode<handout>{
  usetheme{default}
  setbeamercolor{background canvas}{bg=black!5}
  pgfpagesuselayout{4 on 1}[letterpaper,landscape,border shrink=2.5mm]
}

which in particular gives you 4 slides per page, and some nicer formatting (shaded backgrounds, for example).

You can also use

documentclass[trans]{beamer}

which disables all the uncovering, but otherwise leaves things very much like in usual beamer mode.
