I was under no illusions- a colour, PostScript compatible laser printer, for this money wasn't going to be the best in the world.
I plugged it into my home network, and installed the software from the CD onto my PC. It seemed to install a huge amount of stuff. And it worked. Print quality was acceptable for letters, although everything with a tint was very heavy on the yellow.
Then I installed the software on my Mac. Initially it went well, and was soon up and running. However, some of my software required a PPD file. This wasn't on the disc, or Samsung's website. I eventually found it on the PC partition of the CD (which is hidden from MacOS - good job I had a PC too!)
Then the problems started. Try as I might, printing from certain applications resulted in all fonts defaulting to courier- a problem which I still haven't solved. Paper jams were common, until I discovered that I had to set the paper type frpm "default" in the print dialogue box (I didn't have to do that on the PC). Next, the print quality was awful. Very oversaturated with yellow (worse than the PC- even black text had yellow on it), and often the toner didn't fuse to the paper properly. Further experimenting with the paper type options fixed the latter problem.
This is the first time I've had more more problems with a Mac installation than a PC.
So... if you're got a PC and want to use it just for letter writing, buy a printer without the PostScript functionality - it will be cheaper. If you've got a Mac, AVOID!
