I bought this printer and used it to print up material away from home twice. Then after I had plugged it in at home there was an explosion when I tried to connect it to the USB port of my computer. Our satellite TV quit working immediately, the input had been blown and had to be replaced. Our 42" Plasma TV (2 years old) quit working a few days later. Strangely the USB port where the explosion occurred seems to be fine. I had enjoyed it until it proved to be very faulty.
