These are ink cartridges for an elderly and basic printer that still works great. I am glad HP is still making the cartridges, though it would be nice if they weren't so extremely expensive.
This product does work in my 1210v printer, and it will probably continue to work until the 6/2020 expiration date on the package. However, the price for non-expired HP black ink is outrageous, and it is clearly an impractical buy for a color ink cartridge. I should have purchased a whole new printer instead, and it may not be HP next time.
I have bought 2 new sets of cartridges 22 and 56 for my HP Officejet 5610 All-in-One and my printer tells me that are not compatible for it. I always have used the same, except that the lattest 56 does not look like the previous ones. They used to be black outside and now they are brown.
