Ever wondered how to avoid the overlays when you want a printout from your beamer presentation?

Just put the handout option in your beamer presentation.

\documentclass[12pt,handout]{beamer}

If you then want t o also print everything on one page (as Steve did for his Away Day talk) then just do this

\documentclass[a4paper]{article}
\usepackage{pdfpages}

\begin{document}
\includepdf[pages=1-last,nup=2x2,landscape=false,frame=true,
            noautoscale=true,scale=0.6,delta=0mm 5mm]{mypresentation.pdf}
\end{document}

where mypresentation.pdf is your beamer presentation which you created with the handout options (so without overlays). In this example 4 beamer slides are printed on one page (2x2).

For more convenient switching between beamer modes, you could also try the beamerswitch class. For your regular presentation:

\PassOptionsToClass{12pt}{beamer}
\documentclass{beamerswitch}
\handoutlayout{paper=a4paper,nup=6,align}

To produce a 3x2 A4 handout of the slides (as specified by \handoutlayout) without all the overlays, simply add a class option:

\PassOptionsToClass{12pt}{beamer}
\documentclass[handout]{beamerswitch}
\handoutlayout{paper=a4paper,nup=6,align}

The class also has some tricks for outputting both the regular presentation and the handout (and possibly other variants) in the same LaTeX run.
