I already had a Canon printer "basic", which worked very well making a lot of noise. She stopped suddenly to a power supply problem. Block found food, most expensive repair the machine ... Hence buying a new printer, less basic, a bit more expensive (but discounted), which presents the eye better, better finished with duplex printing. Beautiful appearance, glossy black walls, still in running noise, but the whole is better finished than the previous printer. Value pretty good. As for sustainability, it will take a few months to enjoy it
