This new product from HP has an HP Code CN684WA with a standard page yield of 550 pages. The previous stock Code CB321WA discontinued in October 2010 had a standard page yield of 800 pages.

I installed the new ink cartridge, and the indication from the printer shows its not full. I didnt expect this, buying directly from HP. I probably wont purchase from HP again.

I get fast and friendly service when I shop at Office Depot. I like the fact I can get the HP ink in a variety of packaging--color pack, single pack, Black and color, This time I only needed a single magenta. Appreciated only having to pay for what I needed. Good ink!

Clean Replacement; dries quickly; easy to replace; Sharp Tones & Colors

Short Cartridge Life; value

This regular black cartridge has a even lower page count as advertised and won't last long. They do work fine. For longer lasting cartridge get the XL one instead. Buy this cartridge if you don't print much or you just simply need the lower cost.

It's ink. It works. My B8550 printer uses too darn much of it!!! So now I'm looking for a good color laser printer - so I can spend even MORE on printing consumables... :-( PS: Whatever you do, use a coupon!

As expected with brand name HP purchase. Expensive. Might as well buy a new printer.

....I mean literally. I needed to print a number of photos from my HP at home. It's something that I don't do that often. When I inquired about the necessity of this additional cartridge I was told that it was required. I got home to find there was not spot for it in the printer.

So I brought this around June 1, 2018, for my home. I don't print very much (concert tickets, return slips, occasional instructions), so about 20 pages since I about the ink. I took the ink cartridge out shook it put it back in and still nothing.

I like the quality of this ink & its easy to install. I save some money by buying the XL printing capacity so I don't have to change ink as frequently

I like the XL printing capacity

all is good about it

every time i buy ink cartridges i have to wonder why this stuff is so expensive. the only answer that makes sense is that they mine it from the ocean floor under the arctic.
