The highly retro monochrome laser printer, Samsung ML-1610, continues to work just fine on macOS 10.13 High Sierra. However, getting driver support took me a long time to figure out a while ago. I got something worked out for macOS 10.12 (Sierra) and posted about it here.
To my great surprise, my old post on getting this going has become the most popular, heavily visited post on dawning.ca. So… I’ve revised things and spun this in to what I’m calling “ml1610-blaster”. There’s a github repo hosting it, here: ml1610-blaster.git
