psdim is a small utility to be used in conjunction with pstops.
It looks at the contents of a postscript document to determine the
size of the printed pages. From this, it calculates the optimal
placement of the pages for n-up printing. It outputs a format
string suitable for processing by pstops.
Flavors:
