You have to either go back to the driver that worked for you or complain to Samsung about it. They won't know unless folk complain.
This is one of the reasons Richard Stallman became a force for open software.
While the long version of the story is at https://www.gnu.org/events/rms-nyu-2001-transcript.txt the TL;DR is that at first the printer code was open and free to change to their needs. When they locked it down, Richard Stallman began to think a lot more about open source software.
Since installing a new driver for my Samsung M2026 Laser printer from the HP site on 09/12/18, I cannot get the Eco settings to save. I have to go into Eco settings every time I want to print a document and click on a favourite I have saved. If I then go to print something else and click on last used setting it doesn’t remember.
I go to print
Eco preview printing
click on the one I’ve set up
It’s such a long way round and driving me crazy.
