/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.
