I have a Xerox Workcenter 3025 which I succesfully used on Windows. I recently switched to Mac (Big Sur), but even though I installed everything exactly like I used to on my old laptop, when I try to print something the two-sided print doesn't show.
I read somewhere that I have to go to Printers->select the printer->Oprions and Supplies->Option. But when I reach the last step, I can only chose "general" or "supply level". There is no "options" tab.
Did you install the Xerox Print Driver or the driver that came with the macOS? I would recommend trying to reinstall with the Xerox Print Driver.
I have very same problem as OP.
I am using MacOS 12 Monterey and have installed drivers from offical website, version is: https://www.support.xerox.com/en-us/product/workcentre-3025/downloads?platform=macOS12&category=&lan...
On Windows I can manually print two sided with the help of printer's guide. On MacOS I cannot print two sided, option is not available at all.
Is this indeed limitation on MacOS or there must be additional instalation/setting?
