One page per side of a sheet. This is the simplest imposition style, and a good starting point if you just want to print your pages with custom margins or on a specific paper size. It’s also useful if you’re using Octavo to clean up some PDFs, and want to output them just as regular pages rather than making a booklet.
Each source page is printed on its own sheet (or on one side of a sheet if double-sided printing is enabled).
The orientation of the output paper.
Enable this to print on both sides of the paper. Pages are paired in order: page 1 on the front of sheet 1, page 2 on the back of sheet 1, page 3 on the front of sheet 2, and so on.
Octavo handles the printer duplex settings for you based on the paper orientation and spine edge.
If you’re going to export a PDF rather than printing, then of course duplex settings don’t matter. Ticking Double-sided Printing enables symmetric inside/outside margins, rather than left/right margins, so if you’re going to have unequal margins then this setting does still make a difference to PDF export!
