  (*
    Displays the standard DialogBox for printing and prints all
    recent output which has been produced on a Dialog Machine
    window between the calls to the procedure
    DMWPictIO.StartPictureSave and DMWPictIO.StopPictureSave by

    Displays the standard DialogBox for printing and prints the
    text which has been produced on a Dialog Machine window between
    the calls to the procedure DMWTextIO.StartTextSave and
    DMWTextIO.StopTextSave. The whole text is printed with the font
    font and the size fontSize.  Pages will be numbered at their
    top right corner and the current header texts will be printed
    on top left corner of each page. Header information will be
    separated from the actually printed text by a line.  If
    tabwidth > 0 then the character TAB (ASCII hc 11C) will be
    replaced with the proper space before the next character will
    be printed.
