The driver, ver. 2.91.00 for MacOS 10.15 Samsung Xpress M2830DW has disabled duplex printing for Word documents. Please fix.
I Installed the latest driver, ver. 3.91.00, for Samsung Xpress M2830DW on Mac OS 10.15.6 (Catalina) , which now allows me to print, but 2-sided printing in Word for Mac (ver. 16.40, MS 365) has been disabled. Only manual 2-sided printing is available. I can print PDF's double-sided. I can save the Word Document asa a PDF for a work-around. Please fix as soon as possible.
