Booklet Cover and Booklet Insides are not available if there is no way to arrange pages using the current page size and orientation in a way that the printed pages can easily be made into a booklet.
If you see the "page size is not recommended", you must choose a different page size and orientation in the Edit tab.
You might notice that the page size you set in the Edit tab is not the recommended paper size.
For example, if you have an A5 Portrait book, A4 is the paper size you need. This is because A5 pages can be printed two on each side of an A4 sheet of paper in the right order to make a booklet when folded.
