This is the fully loaded model of the M451 series machines. This unit comes with duplex and the wireless print functionality. Again, I like this machine. For the money, there isn’t too many other machines that have the print quality that this machine does. However, I just have a hard time getting past the print cartridges. If you have a kid in school or want something at home then I would recommend this machine. If you plan or 4 or 5 people using it and doing a few thousand a month then you need to move up to a machine with larger print cartridges because this machine can become expensive to operate.
