Installing old Samsung printer drivers on latest macOS
There is no drivers available for the latest (for now Tahoe 26.5) macOS for old Samsung printers.
There was universal driver that worked for ML-1600, ML-1800 (1865) series and many other Samsung Printer Drivers v2.6 for OS X - Apple Support. And according to this Samsung ML-1860 and latest MacOS - Apple Community thread that driver is still working fine except you cant easily install it because of OS version limitations in installer.
To deal with this I've unpacked it using manual. Removed version checks (edited Distribution file with in text editor and added "return true;" on lines 31 and 47). And repacked it again. After that installation went without any troubles.
Got mine ML-1865 working again without any additional software needed.
If you're not familiar with terminal drop a comment and I'll upload repacked version somewhere (if it's not against community rules).
