One way of doing it would be to print the odd pages first, feed all of them back in, and then print the even pages. It's not quite as concise as a single command, but it would be a lot quicker than authorising every individual page manually.
To do this: in the "Print" menu, go to the "Page Setup" tab. Under the "Layout" column of that page will be a box marked "Only Print". There, choose "Odd sides" and send the print job off - wait for it to finish, invert pages as necessary and then do the same again with "Even sides" (remembering to check the paper tray for the last page afterwards, if your document has an odd number of sides!)
This is the best solution I can think of for emulating duplex printing - it could have some issues if you want to do many-to-one printing, but for one-page-to-one-side it will work fine.
For many-to-one (say, if you want 2 pages to a side), you'd need to put the page sequences in manually - i.e. in Range on the main print page, you would type "1,2,5,6,9,10,..." the first time, followed by "3,4,7,8,..." the second. It's not perfect, but it'd work.
