It appears that the 2026 is identical to the 2020, and the same as the 2022 except with a slower processor and less RAM. So I continue to assume the 2020 driver is correct.
That leads me to think that one of the following is true:
1. The printer RAM is too low. I've seen this with other Samsung models from Linux, where a small amount of printer RAM made it impossible to print anything other than very simple documents.
2. Despite all appearances, the printer isn't really the same as the 2020, and there isn't a driver for it in Linux.
3. Something is wrong with your printer. The way to test this would be try to print from a Windows or Mac machine using those drivers. A virtual machine would probably work if you have one handy.
4. There is some minor issue in the way the driver is packaged, and you should install the driver using the direct Samsung installer instead of the packages.
If you can't do #3 and/or it doesn't help, and #4 doesn't help, then you probably will have to contact Samsung or consider an alternate printer.
