I purchased these printheads for my HP Officejet Pro 8500A Premium.  Ad says it's compatible - NOT!
I tried every technique possible to get them to work, but the printer shows "Printhead Problem - the following Printhead has a problem for both MC and YB"
Buyer Be ware!

They are not compatible with my HP Color Laser Printer 4700dn. Even though they say they are!

I keep getting a message that says "UNAUTHORIZED SUPPLY IN USE."

The Magenta cartridge comes out Yellow.

I only needed too replace 2 BUT bought all 4 thinking I will save money down the line. Not so.

Now I need a laser printer specialist to come and do some color calibration. Just more headaches and more $$$.

Or I need to ship them back which means more time and more money.

Very unhappy.

this is the incorrect part for the HP LaserJet 1100.
Item cannot be used and seller will not replace.
Perhaps listing the actual size of the end of cable would assist in determining the fit.
This cable end is about twice the size of the HP connection.

Doesn't work with my HP Officejet 4635. Machine won't even print. Printer uses 61XL ink...wouldn't accept the tri-color. Haven't tried to put the black ink in yet.

Price was very reasonable but the printer came up with a code that said they were not compatible.

Does not work with my printer, that I usually use HP 920XL in. Pages come out so blotchy they are not legible.

This does not actually work in my HP printer even though it says it will.  And I didn't put it in until today, so I didn't know, but it is now too late to even return.

My HP Laser printer did not like recycled ink cartridges. It wouldn't recognized them at all.

Cable is well made, but unfortunately, it did not solve my problem of making my HP4 laser printer work with my new computer that uses Vista. Suspect it is a lack of Vista compatible drivers from HP that is the source my my problem. So the cable will go into my box full of things I no longer need. Too bad,.

Was not accepted/recognized by the HP printer that I bought at the same time - despite the fact that it says they work together.
Subsequently read review that say it's the printer that is out of date. Bummer - so now I am throwing away the brand new HP printer I bought and buying an Epson.

These remanufactured ink did not work on my HP printer,  in fact they killed it and had to buy a new printer. No more generic inks for me.

My printer gave me a notification that it's non-HP cartridges, but somehow I was still able to get it to work.

ended up not working in printer, after some research discovered that printer did not recognize it as HP quality ink
