Bill,

The ps driver hardcodes in sizes of 8.5x11 and 11x17 for
defining the paper trays of printers. Other than that, the
size information is ignored in the psopen.c routine which defines
the scaling as "0.03125 0.03125 scale".

You could either change that code logic and use the size information, 
or, add a line to the ps.plt output file that defines a new scaling 
for a smaller print.

In the ps.plt file, just after the %EndSetup and save lines, you
will find a line such as:
 .50 inch .25 inch translate 0.03125 0.03125 scale
(th

To shrink the resulting plot an additional 50%, you can add a line
immediately following the above scale line such as:
 .5 .5 scale
