    My hp l25500 is still running strong. But as you know, they’ve discontinued the parts for it. I can’t find decent printheads anywhere. Tried a couple of Chinese companies and they are terrible! I discovered that the 792 cleaning kit cartridge works in my 25500. But I was also wondering if the 792 ph’s might work with the 25500 as well? Anybody tried?
    Thanks!

    Would not. The ink type is written on the chip.

    I wish HP would be less black and white and allow people with obsolete machines to get a firmware update to run the 26 series heads and ink. They are exactly the same other than the ink is glossier.

    I want to point out that hp has been using these printheads everywhere. The first time I had to replace one in my l25500 was when I realized it was the same as the officejet we had in our office. Even the cartridge is essentially the same, just scaled down to 1/10th the size at 1/2 the cost.
    So have you tried the chinese chip out of a l25500 printhead in a new HP official 560 printhead?

    The 3 & 5 series heads won't work because the color mix is wrong and the loaded ink is not the same. You would have to reprogram the ink firing order to get those heads to work.

    Do they prime the heads in the factory? I mean if the hardware is the same, which I know it looks the same but I'm not an expert, then would it really matter if you put a cyan/black head from a 560 in a 25500 yellow/black slot, as long as the chip says the right thing? I mean swapping chips could theoretically be considered 'reprogramming' the firing order of that given printhead...
