/LINES=lines_per_page

    This is the number of lines to appear on a page, starting at the
    top margin. By default, PS merely attempts to place as many lines
    on the page as possible; each line displaced vertically below the
    previous line by amount font_size * spacing_factor; font_size has
    the default value of 12 points (10 points for FAXes) and spacing_
    factor has the default value of 1.
