Without wanting to exaggerate: The printer is perfect. I use it on Mac OS X, after installing the driver CD everything works fine. Print speed at least as good as given, felt more quickly (from "OK" to the final document, it takes me no 4 seconds). Even large amounts of pressure to go with massive speed vonstatten. Simply remarkable. The printer is still manageable without end, hardly takes up space. While the pressure is a little bar on the screen at the level that is apparently never less, and I really prints daily and sometimes quite a lot. Color documents are output without conversion time in grayscale, again, no defects, rather even better than expected. The print-on-screen function works flawlessly and as described. Although I have not yet registered to mind so completely, but if I should even come into such a situation, I know that the function is working as it should.
Thank Samsung, for this great product, which I really many many many hours of trouble, frustration and cartridges search unnecessary.
The only question which makes me: Why have I not been resorted to a laser printer? Buy! And no, I'm not a Samsung-copywriter.
