Print symbol '*' only on blank pages.
Now user need summary should be printed on Next page(This is achivable). and symbol '*' should be printed on blank pages after Detail & detail.
e.g Detail infomration filled 80% of page then remainig 20% page should be filled by symbol '*' and if 100% page is filled by detail then no '*' is printed.
Also same case with Summary. Summary always start with new page. once summary printed. reamining page should be printed by symbol '*'. If all page is blank then symbol '*' should not printed
