A dynamicalsystems package question



I wonder if there is a way to send the output of a drawing from the
dynamicalsystems package, say 
   staircase(2-0.3*y,1,10);
 directly to an EPS file, instead of displaying it in an openmath window?

I know that I can save the picture into a postscript file, and then
convert that file into an eps file, but I am not too happy with the
eps file obtained this way.

Thanks,
