Gwen This morning I installed my Samsung printer onto a computer with a clean install of Solus Plasma 4.5 with all updates applied.
The printer installed without issue after I followed the following procedure.
Connect printer to PC and power on.
Unzip drivers file.
Open the new drivers folder in terminal.
sudo bash install.sh
Press enter to list through terms agreement
Type yes
Type y
Type N to skip firewall setup
Printer will install.
Go to Print Settings in main menu and install using detected printer and installed drivers.
When installing the printer there was an error message about Cups not restarting but this did not prevent the printer from working and printing a test page.
This test was carried out on a USB connected Samsung ML-2168 Printer.
The install instructions have been modified to work for your printer on any of the Solus flavors.
Good luck.
