function pj = printprepare( pj, h )
%PRINTPREPARE Method to modify a Figure or Simulink model for printing.
%   It is not always desirable to have output on paper equal that on screen.
%   The dark backgrounds used on screen would saturate paper with toner. Lines
%   and text colored in light shades would be very hard to see if dithered on 
%   standard gray scale printers. Arguments to PRINT and the state of some 
%   Figure properties dictate what changes are required while rendering the 
%   Figure or model for output.
%
%   Ex:
%      pj = PRINTPREPARE( pj, h ); %modifies PrintJob pj and Figure/model h
%
%   See also PRINT, PRINTOPT, PRINTRESTORE.
