I was so happy. The last time I tried to use an alternative cartridge for my HP it didn't work at all and I got a message saying it wasn't an HP cartridge, so with some trepidation I decided to go with the Greensky and WOW -Trying cartridge which made me very happy Discover it works great! No questions. No news. Sheets printed page by page only. It's a lot cheaper and I love to print! Can't speak to Longevity because I'm still on cartridge one, but looks like we've got some great shotguns. As a real estate agent I write a lot and always print out all my transaction documents as well as the listing and property pages.
