They do. I got a Samsung C480 colour laser printer, scanner, copier a few weeks back to replace a broken Dell. The cartridges are far more accessible than the Dell. All three functions are reliable so far; so it's been a good buy for 208GBP. I'm becoming something of a Samsung loyalist. My Ultra laptop is still going strong after nearly four years, as is my 3 yr old Galaxy S4 phone and 10 yr old flat screen TV.
My Samsung SL-M2020W/XAA was killed by a simple paper jam. There was literally no way to get it open to reach the shreds of jammed paper inside - one-way plastic tabs etc. Only time I've ever gone Office Space on a piece of equipment.
My family owns a CLP-315W Samsung Color Laser. It's been in service for years, has fantastic network support for Windows, OSX, and Linux, and a lot of the parts are interchangeable (even the Drum / Imaging unit can be replaced by the end user).
I dread the day I'll have to replace it, but until it keeps printing like a champ.
