"Both printers have similar pricing, although OKI claims 12ppm in colour and only 5ppm for Samsung. We will look at the speed test results later to see how close is their claims. On the other hand, Samsung is capable of 21ppm in mono, which is slightly faster than OKI's 20ppm. Samsung came with twice as much RAM as OKI, but the processor speed is slightly slower. However the actual print speed will depend largely on the efficiency of the firmware and drivers, not only the processor alone."
