Once you select a system, the program runs through each of the suns and worlds 
in turn, printing out the data that would normally be produced by pressing "P" 
after generating a planet map.  It runs  fairly  quickly  because  it  doesn't 
display  any  graphics,  apart  from  the  simple  solar system map.  The main 
limitation is the speed of your printer;  if you have a  buffer  card  in  the 
printer, or run a spooler program, it only takes a few seconds per system.
