please tell me am i thinking right
about this method: setImageableArea(.....)
public void setImageableArea(double x, double y,  double width, double height);
like I said, I've tried this method and it doesn't seem to do anything.
the width=the JFrame Width,the height=the JFrame Height right?actually, when printing, 72 points (printing version of pixels) = 1 inch, so to do WYSIWYG, you need width = JFrameWidth * 72.0 / Toolkit.getToolkit().getScreenResolution. Ditto with height
upper left beginningx(0)---------------------------200--------------------------------600-----------------------------------y(1000)upper right beginningyou need to do something like PageSetup.getImageableX and do Graphics.translate(x,y);
also, if your page width = 720, that = 10 inches - that's a wide page (unless its in landscape)
so if i want the JFrame To Be In The Center Of The Page I Would Choose From x=200 ,y=600 depending that frame width is 400Actually, it would be 300 - 700 in your example
Because when i tried to use:setImageableArea(200, 600,  400, 200);like the above code
no changes occurs in the printed paperYes. You need to offset the Graphics object
