>You are correct that the CSS2.1 test suite assumes that the OS is
configured to believe that the display is either a 96dpi display, or a
display whose resolution is "very different from that of a typical
computer display". It makes a series of other assumptions as well,
including the following:

Another large assumption made by the test suite is that custom fonts are
installable (such as the Ahem font).  You may wish to add this
assumption to the README.  For all of the printer UA's of which I am
aware, this assumption breaks.

Best wishes,
