As Bruce Langdon pointed out, a sufficiently clever PostScript
DVI processor can cause the page to be scaled however you like.

To clarify one point, when you print pages two-up on 8.5x11-inch
paper, you are not scaling the font by half; half-scale fonts would be
useful for printing four-up.  Instead, you want to scale by a factor
of 5.5/8.5.  The resulting page images cannot quite visually represent
a full page, however, since the proportions of a half-page are
different from those of a full page.  The result is that the vertical
(typically bottom) margin of the half-page image will be
proportionally larger than that of a full page.  Or you can make the
vertical margin correct but make the horizontal margin narrower, by
using a different scaling factor.

Consequently, if you intend that the two-up pages be visually correct,
rather than merely useful as compact `preview' copy, you must adjust
your margins in your TeX source code to account for all of this.  If
you intend that the text appear at full size (e.g., 10 truept),
further magnification issues may come into play.

European DIN A- and B- series paper (such as A4 paper) has a useful
proportion of \sqrt{2}:1, so that when folded in half, the proportions
remain the same (and produce the next standard sheet in the series; A5
is A4 folded in half).  An enviable situation.
