Hello, on my Xerox WC 6027 I am not allowed to two-sided printing. According to user guide on page 136 this option is available for this printer. I am running macOS Big Sur ver. 11.2.3 and driver for printer is ver. 1.150
I see no one has responded to this post yet. So, at this point I would recommend contacting your local Xerox Support Department to speak with a Product Specialist for more assistance. Please call 1-800-835-6100.
Thanks, TammyL-Xerox Community Manager
