Well, PostScript uses a single "master" (ie, character shape definition) for all
point sizes, so you don't actually get different shapes for different  sizes. 
Therefore, you can easily take a 300dpi PostScript printout, stat it down, and
treat it as 600 dpi.

Other than this, I don't know of any systems which do deal with multiple
masters, except for phototypesetters.  If you have a phototypesetter, you're
already getting high resolution output.
