[This review was collected as part of a promotion.] I have a very old (but good) HP printer. I can't find the ink in stores anymore but it was so easy to look up what I needed, place order and receive it in a very short time.
I purchased the wrong ink. I purchased 78 tri color. instead of 951. I reordered the correct ink and printing well now. Too bad I had to toss the 78 ink. There expensive.
[This review was collected as part of a promotion.] I tried a knock off refill for my printer and kept getting n error message saying to replace incorrect printer .cartridge. I replaced it with an original HP cartridge and the printer works fine
