Rated 5 out of 5 by Anonymous from Works perfectly. Nice, clear print. But these cartridges do dry out, so if you only use your printer sporadically, remove the cartridge and store it in a plastic zipper bag.

Rated 2 out of 5 by Anonymous from HP 21/22 Inkjet Print Cartridge Combo I had to return the last cartridges I had ordered from you, because the color cartridge wasn't printing correctly. The color cartridge I received as a replacement isn't printing correctly either. Half of the color sections are printing purple and they shouldn't be purple. I'll find another place to purchase my cartridges from now on.

Rated 2 out of 5 by Ret Col J from Fewer printed pages than advertised The HP inkjet cartridges we have purchased have consistently provided fewer printed pages than advertised. They seem to be "empty" before they really are out of ink. They also seem to "clog" and stop printing altogether if not used every few weeks. Only rarely will the "clean" routine unclog the print head. [Some other brands seem to be OK even after being idle for six or more months.]

Rated 1 out of 5 by Brizo from New HP21 Black ink cartridge will Not work I purchased a new HP21 Black Original ink cartridge, and my HP F380 printer will not accept it. I purchased 2 more HP21 Original ink cartridges, and my printer will not accept any of them. My investment in 3 defective HP ink cartridges would almost purchase a new printer. My printer works fine with my old cartridges, with no error message, but they are all out of ink. All 3 of these new HP21 ink cartridges are made in Malaysia, and they are obviously defective. If I can not purchase HP ink that my HP printer will accept, you can see that I might not purchase another HP printer.

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.

Can I use 2 #21 black cartridges instead of one #21 black and one #22 tricolor in my HP desk jet printer F4180?

Asked by: Anonymous
Thank you for your question! No, you can print using only the black cartridge, but when two cartridges are installed there must be a black cartridge and a color cartridge in the correct slots.
