Stay away, the printer does not recognize it at all.
Now it shows the problem that appears in the screenshot I uploaded and no matter what I did, the printer does not print.
It seems that the original ones are the only way.

These inks are not for amateurs!!! Those who are not working need to do a downgrade!!! With these inks, the head requires a bit more cleaning!

Tragic quality! It's as if it has water instead of ink inside. I bought it for the Officejet Pro 7740 as a test to avoid the huge cost of the original, and the result was just a smear. After printing 10-12 pages, I took it out and put the original back in. I had to do 5-6 head cleanings for it to return to normal, and it's worth noting that I didn't use a full set; I only used the black.

It worked fine for me. Of course, the printer found that it is not genuine, but it prints normally and in good quality. I haven't updated it for that reason.

The ink is a relatively decent compatible ink with all the things that connect the compatible ones (slightly lower performance in quality and quantity). There is no significant difference from the other compatible inks and the MOST IMPORTANT thing that applies to almost all compatible inks is that with the latest upgrade, HP has locked the non-genuine inks, resulting in an ERROR message "non hp chip detected". The only way to resolve the issue is through a USB downgrade. You will find many guides and videos on the internet. But is it worth it? For me, the answer is simple: The machine costs: €280.00, genuine inks: €165.00, and compatible inks: €37.00. Which means I save about €130.00/change, so in 2-3 changes, I have a benefit greater than the value of the machine, always with the risk that accompanies this choice. For me, it is the only way, but everyone operates as they see fit.

Connection after many attempts. Very poor printing from all colors. Unfortunately, you can't escape genuine inks here.

It doesn't work, I don't recommend it, it doesn't recognize it at all
