I'd ask Samsung how to install the firmware dated Dec 23, 2015 at http://www.samsung.com/us/support/owners/product/SL-M2885FW/XAA
That's very fresh and I see software has a 2016 date there too. I'd get up to date on both items.
Samsung support in the USA is 1800SAMSUNG.
Was working fine until two days ago. Samsung Xpress M2885FW Mono Multifunction with Win 7 desktop. The printer copies, scans to computer but won't print anything from the computer. I unplugged power and usb and reinstalled cd that came with printer. Any help would be much appreciated.
