I checked, these number are the same on my Linux box, but there the printout is ok. It seems to me Cairo/Pango somehow does not realize that on the Mac, all printers have a virtual resolution of 1200DPI. I googled a bit but could not find anybody else having a similar problem or even a solution. Thus I would suggest (unless somebody has a better understanding what is going on with Cairo font sizes on different platforms and devices (screen is ok, so are the fonts in the plot, just not the text in the boxes below) to include a fudge factor in pango_font_description_set_size that is nontrivial (about 1/20 = 0.05) only on Macs.
