I use this ink in my HP Photosmart P1100 color printer. Great results especially when used with HP paper. But for the best value, consider buying the high-capacity cartridge. The model# (SKU) for that is C6578AN. The cartridge is the same physical size, but it contains more ink. But whatever you buy, be sure to store it UPRIGHT. That helps prevent bubbles or air pockets that can form inside which can cause imperfections on the printed page.

We purchased 2 color ink cartidges back in November. In our dental office, we order in advance and we don't use color ink much, being that we print mostly xrays. Both cartidges were missing yellow ink so we could not use. We asked for an exchanged and they said "no" b/c of a 30 day return policy. They were not budging, not even willing to replace one being that it was the first time ordering from that company. I even told her I'm never ordering from them again and writing a bad review, she replied "ok". Well, here's their bad review!

I received my order today of two (2) HP 78 color printer cartridges for my vintage HP 1220C. Neither of the printer cartridge worked; absolutely no color on the test pages except black. I was extremely disappointed to discover the dates on the cartridge boxes were May 2007 and July 2007. Obviously, the cartridges, and ink contained in them, has a life. These were knowingly sold well past the date on the box (5 years!). Extremely disappointed!

Honest reviews on HP 78 Tri-Color Printer Cartridge (C6578DN)

I've owned a HP printer which required the use of the 1823D cartridge, and this cartridge seems to be a vast improvement over that one. I'd estimate that it seems to print about 30-40% longer than that earlier-designed HP cartridge. Of course that could be put down to the printer itself, but the point is that I get more life out of this cartridge than my last ones.

This is moderately good news for anyone, like me, concerned about the monopolistic nature of ink jet cartridges in general. While I generally think that the Justice Department would be better-served to spend time investigating the monopoly of ink-jet supplies than Microsoft, at least it appears that HP is trying to improve their products.

Out of completeness, it should be pointed out that the Amazon description, above, fails to mention that this is the cartridge for the 1220 series as well as the 900 one.

I purchased the tri-color ink cartridge. It would not print vivid colors such as red and yellow. I contacted HP and they insisted that the problem was the (HP)printer that they consider obsolete. I swapped out the old low level HP tri-color cartridge and it printed perfectly. Replacing the old cartrige with the new one produced the same results with the colors not printing. They recommended purchasing one of several other HP printers that use the FHP 78 tri-color ink. Then if the new cartridge still printed muted colors, it could be the ink cartrige itself. HP would not recognize that the cartridge could be defective in my printer. HP did not try and replace the ink or admit that the ink could be the problem. Very poor support for an expensive product (the ink costs $60.) It seems I would have been better off purchasing it at a big box store at a higher price with the hope of better service.
