The "screen versions" are either the Beamer slides of the talks or versions
made with the handout option to Beamer, which simply ignores pauses
and produces one page per frame. My default Beamer font is Palatino, using the
mathpazo package.
The "print versions" are produced as follows. If the output from the screen
version is called x1.pdf, then run pdflatex on the following
input file:
\documentclass[a4paper]{article}
\usepackage{pdfpages}
\begin{document}
\includepdf[pages=1,landscape=false,frame=false,noautoscale=false]{x1.pdf}
\includepdf[pages=2-last,nup=2x3,landscape=false,frame=true,
noautoscale=true,scale=0.7,delta=0mm 5mm]{x1.pdf}
\end{document}
This puts the first slide on the front page and the others 3 rows and 2 columns
per page.
Note that the filename occurs twice!
If you don't have a handout version of the slides, note the numbers of the
last slide of each frame and put the list of these numbers in place of 2-last.
