The "screen versions" are produced from the Beamer slides of the talks using
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!
