Since I usually produce PDFs through dvips->ps2pdf I am probably not the
best person to answer this. I'd assume producing single-page EPS files
and shoving them through eps2pdf?

A (suboptimal) solution would be to produce high-resolution PNGs
(-D 1200) and shrink them to the appropriate size. This would probably
look terrible onscreen but better on the printer. I don't know enough
details about the surrounding system you use to be more specific.

I wrote that. And part of the WikiMedia code. Problem is, PNGs are pixel
images, there is just no way around that. The solution would be to use a
vector-based format.
