MICR Toner at a great price! I have HP P1102W. I looked around and it was the lowest price I could find. However, I was a bit skeptical about buying toner from Amazon. I bought some ink cartridges from another seller and they were just awful. However, my experience with the MicrPro was amazing in comparison! Free shipping and it arrived in about 3 days even without Prime. I had a bit of trouble putting the cartridge in my printer because the valve wouldn't pop off as easily as the regular toner that came with my printer. But after several attempts everything went smoothly. There was a stain that printed for about 10 test prints but then disappeared. I'm not sure if this is because I had trouble installing the cartridge or if it happens with all new toners. I think we'll see when I have to buy another one. All in all I would definitely recommend it and buy it again.
