Printing one Pages-page twice on a physical paper?
While I don't use Pages.app the macOS print dialog box is pretty standard and that option is to be found in most apps.
In Safari (below) when you go to print, you get this when you select &quot;Layout&quot; from the pop-up menu halfway down the dialog:

You merely need to select 2 pages per sheet and will print a single page &quot;two up&quot; as they say. Note that if you have a two (or 3 or 4...) page document it will print page 1 and 2 on the first sheet of paper.
