Rated 3 out of 5 by Huna from Old printer still works great My old printer still works great. However, One container of black ink costs me as much as the printer did. why so much for half an ounce of fluid?

Rated 5 out of 5 by maryand5653 from Great cartridge replacement I have bought ink from retailers like Walmart before. Due to the shutdowns and quarantine, I can't get to the stores now. I decided to buy direct from HP. Great service. I won't be going back to retail anymore.

Rated 5 out of 5 by MikieW from Ordered my black ink cartridge direct from HP While trying to print out an income tax form I ran out of black ink. EZ Peazy to re-order directly from HP, shipped for free and I had my new cartridge in two days and cheaper than Target or Walmart. You really can't beat that convenience !

Rated 5 out of 5 by Marylou53 from Old but great printer I've had my Deskjet F300 Series printer for many, many years and it's still operating like new. I'm so glad I can find the printer cartridges for it, and it's very easy to install which is great for someone like me who isn't very techy. :)

Rated 5 out of 5 by AndrzejG from Great cartridges Bought HP21/22 cartridges for my HP F380 printer used for more than 10 years. They're easy to install and lasting for some time when used at home. We're happy with black and color prints. Probably we'll upgrade to never printer in future but will stick with HP brand.

Rated 5 out of 5 by hellen4wheels from Original Ink My laptop is HP. My monitor is HP. My printer is HP, so why would I buy any other ink? Ordering is quick and easy. Shipping is free. I don't see any downside to this at all. I rely on HP daily and I've had no issues at all. It's always best to use original, brand name ink replacement cartridges and with HP it's win win.

Rated 4 out of 5 by ccdeems285 from Better Deal than Walmart We have been purchasing our ink from Walmart for several years with no real compliant (just usually wait too long and need the ink yesterday -lol) So this time we purchased ahead of :got to have it now" was able to get a special promo offer on the price but even witout that there is only a 10 cents difference between Walmart and HP.com BUT the real bonus is HP sends a postage prepaid bag for the old ink bodies - we use to just throw them away - just more thrash filling landfills - great to help do our part and protecting our Earth even if its just this little act Plus being HP ink - there is no issues with them working properly 4 stars instead of 5 - shipping could be a little quicker but again that could be more on us needing to shed that "got to have it now" mindset

Rated 5 out of 5 by tswins from Hassle free purchase. I bought ink cartridges from the HP website last month. The website was user friendly and showed me the right items and the bundling and pricing options available. Shipping was free and I was frequently updated on the status of my order via email. The package and the products within were in excellent condition upon receipt. Overall, I am very pleased with the purchase experience and will definitely consider the HP website again for future purchases.

I have a HP Deskjet 2210 - Do you have a high yield ink cartridge that will work in this printer? I usually purchase HP21 cartridges for the black

Asked by: Alexann
There is not currently a high yield option for that unit. Just the standard 21 black and 22 tricolor options are available at this time.

what is the expiration date

Asked by: M.j.
HP cartridges do not have expiration dates. They will come with a best-if-used-by date. That date is determined by when the cartridge was manufactured and will appear on the product box. As this will vary, no information is available on what the Best By date would be on an individual cartridge.
