After I had very considerable difficulties with the "low ink" a few years ago and that led so far, which was replaced on my printer warranty, original inks only come to apply. I had a compatible ink cartridge used in my printer and the typeface was impossible and unacceptable. A printout or test page I have sent to the printer manufacturer who has sent me a new printer, but not further address this problem. It was only when I reached the same poor printing results with the new printer, I'm even come behind it, that something was wrong with the ink. I have then original printer ink buy, used this and the printed result was excellent. Therefore, I buy still only original Druckertine or printer cartridges.
