I was having problems to make the scanner work too, and fixed the problem.
My printer is configured via wireless but the twain driver wasn't being installed correctly and the universal scan driver was installed but wasn't working properly.
I saw that the scanner driver wasn't configured to find the printer, so i needed to set it manually.
Here was what fixed for me.
Install the Universal Scan Driver
After that press Win + R, copy this line below and click OK
C:\Program Files\Windows Photo Viewer\ImagingDevices.exe
On Scanners and Cameras screen select Samsung Universal Scan and click on Properties. Go to Scanner TAB and click on Change. After that click on ADD. Let the automatic scanner find the printer, select it and click on ADD again. After that click on OK.
And you are ready to go.
