Accustomed longtime Oki products for efficiency and performance, I needed a new printer for my home and this model is perfect, he does front / back, he quickly heated to a laser, and impressions are very well made! Works perfectly on Mac with the driver provided by Oki, which manages all printer options. An optional tray for the front / back are available on Amazon, which makes it possible to really make a very complete printer at a very moderate cost.
