Works great but expensive. I started ordering LD refill cartridges, which work just as well, if not better, considering the difference in cost. We had a couple of simple programs that used a lot of blue. Midway through the 100th run, the 2-inch logo, which should have been dark blue, was inexplicably printed in turquoise. At first I thought there might be something wrong with the printer because the ink hadn't run out after weeks of heavy use, but when the cartridge was replaced we were able to print dark blue again. This may or may not have been the norm for that cartridge, or it may have been a technical issue that those more knowledgeable about the color mixing process in these printers could explain. As for me, I will most likely continue with LD refills rather than re-ordering this particular product.
