Oki. I have used Oki Laser Black & White printers with openSUSE for last 12 years with no problems. Printers connected by Ethernet to router serve 3 openSUSE LEAP 15.1 machines which also operate on openSUSE Tumbleweed when Tumbleweed is started on external USD drives with Current Tumbleweed.
LEAP used for production. Tumbleweed for leisure/browsing/experimentation.
