Landscape in Microsoft Book Fold
According to Lulu.com, the project should be in portrait orientation. In Microsoft, using the book fold setting it only allows landscape.
When I setup the page as recommended, in portrait and using "mirror margins" plus adding a gutter, all the pages are offset to the same side rather than being opposing offset for odd vs. even numbered pages. In the book fold setting it properly offsets every other page in opposite directions for the back to back printing of the pages.
What am I missing please? Or does the landscape orientation work properly in book fold setting because the page is split in two parts?
Thank you in advance for your attention to this matter:
