  Only if you have a printer that supports it. Otherwise you have to do it by hand https://www.businessinsider.com/guides/tech/how-to-print-double-sided-on-mac https://www.businessinsider.com/guides/tech/how-to-print-dou...

    If the hardware itself doesn't support it, how would the software?

      The issue is that the printer manufacturer needs to provide a printer driver for MacOS that gives MacOS access to that printer capability. (One could argue that Apple should write the driver, and they might for very popular devices.)

      Windows approach: Print even pages first, ask the user to move the printed pages back to the printer and then print the odd pages later. The result is ready to be read. In Mac you need to print first one side, move the pages manually, print the other side. But you have to remember to add an extra page if the page count is odd, have caution if an app tries to be intelligent and sort the pages in a different way... In Windows all those calculations are done by the system. It is easy! Just print and follow instructions. In Mac is painful.
