I want to costumise the printable page

Thanks! Now the probleme is the my grid has colored cells loaded from xml and in printable version there is no color.
if I
want to costumise the printable page how can I do this, for example to
put a title in the page or some text or a picture header?

    var before =" any html code which will be inserted before grid data";
    var after =" any html code which will be inserted after grid data";
    grid.printView(before,after);

before and after may contain any HTML ( including to define title of the page )
