I have the cartridge installation, losgedruckt, wonderful! My printer does have bitched that it would not be original cartridges, but that was about all. I could see no difference in print quality. Well I also like the fact that the cartridges are transparent, so you can also see how much ink is still in there and it is not reliant on the warning "low level" right. From me gibts ne purchase recommendation! In the large price difference to the original HP-goods all.
