here's a few scripts I often use for "printing."  printeps is 
especially  useful if you use LaTeX for document preparation.

These scripts will not work if you use subplot( ... ) to generate 
multiple plots in a single window.  You will have to use gset commands 
before using gnuplots multiplot capability.

function printps(filename)
% function printps(filename)
% replot screen plot to a file
% inputs:
%   filename: string:
% no argument checking done - this means YOU mark!

   gset terminal postscript color
   eval(sprintf("gset output '%s'", filename));
   replot
   gset terminal x11
endfunction


function printpng(filename,pngsiz,fn)
% function printpng(filename,pngsiz,fn)
% replot screen plot to a file
%
% inputs:
%   filename: string:
%   pngsiz: "small", "medium" (default), or "large"
%   fn: figure number to convert to png form (default: 0)
% no argument checking done

   if(nargin < 2)
     pngsiz = "small";
   elseif(isempty(pngsiz))
     pngsiz = "small";
   endif
   if(nargin < 3)
     fn =0;
   endif
   figure(fn);
   cmd = (sprintf(" gset terminal png %s color",pngsiz));
   eval(cmd);
   cmd = (sprintf("gset output '%s'", filename));
   eval(cmd);
   replot
   closeplot();
endfunction

function printeps(filename)
% function printeps(filename)
% replot screen plot to a file
% inputs:
%   filename: string:
% no argument checking done - this means YOU mark!

   gset terminal postscript eps color
   eval(sprintf("gset output '%s'", filename));
   replot
   #gset terminal x11
   closeplot
endfunction
