Right -- but the margins defined by the author of the document may be
wanted to be overridden by the one who prints it. (This should not, of
course change any line- or page-breaks, and not any layout relations
within the page elements, but it should allow for scaling up or down
the page image to different page sizes and margins, as needed or
wanted). Again, this is a case where one needs to keep the complete
picture in mind, the complete printing process (from document creation
until the printout lays in an output tray -- all the steps and inter-
actions).
