In December last year I bought this printer cartridge for my HP Photosmart printer. I always buy this number and original from HP. With this I am still a little surprised why it is offered as low. Well, unfortunately I now had to find only that the cartridge, because I did not need the same, has expired since the 12/09/2010 !!!! Mess! The cartridge will print just red. And in various "forums" I've read that this is due to the fact that the cartridge is old and expired !! Stutzig had me already packing to do. The cartridge had been delivered only sealed and not additionally provided with the carton, which may, external expiration date that would have been it. So you should always buy a cartridge when the old one is empty, and not try the cheap route to take - obviously pulling the short straw.
