Finished dry cartridges, long live the toner still operational! You can count on all the time, it is the dream! I used 2 per year is 120 euros ... it's cheaper than these tiny cartridges ... I opted for black and white, I let the color professionals :) No more waste, we return the old toner in the packaging of the new with a shipping label included in the box: twinkling green eyes! And a black and white laser printer it's cheap! I do not take the generic product ... I was got drunk with the cartridges ... I hope that prices will decline further toners :) This really is the ideal solution;) And thank you Amazon, great site!
