To change the scale of a PostScript document, insert a command 
of the following form immediately after %%EndPageSetup:

n n scale

where n is the factor by which the scale of the diagram is to be 
multiplied to obtain the new scale.  For example, 

0.5 0.5 scale

would shrink the document by 50% in each direction, so the resulting
output would occupy only 25% of the page area of the original output.
