Cannot print double- sided in LM 19.3- Cinnamon using Master PDF Editor nor scan both sides of document with the same app or using gscan2pdf. Able to do both in Windows 10.
Have tried doing same through USB connection as per a post I found online but this made no difference. I am mainly wanting to print double sided & after searching online scanning double sided would see more problematic.

A experienced user on the Mint Forum has tried many ways to solve problem but to no avail.

The Samsung “Universal Linux Driver “(ULD) is installed.
This is frustrating as I have virtually moved from Win 10 to LM & this seems to be the last stumbling block to doing so.
Any input on this would be greatly appreciated- Bruce
