how to check or edit line feed all pages

[RobertoVG]

how I can do programmatically check to see if there is line feed in the last line of each page?

If there is no line break in the last line, how do I enter this new line programmatically ?

Thanks

If you insert a paragraph break in places of page breaks, it may change pagination, because SpaceBefore and SpaceAfter of paragraphs will be applied.
