p%! Module Name:  LPS_PS_EXT 
%! This module shows how you can redefine POSTSCRIPT extensions
%! that are used by non-Digital printers to be Digital POSTSCRIPT
%! extensions. Note that for Control-D and Control-Z, you cannot 
%! simply type ^D and ^Z. You must use the actual control codes
%! in the setup module. 
%!
%! Please note that this example is based on North American 
%! (letter) paper size. For Europe, change all the "lettertray"
%! references to "a4tray".
