Rated 5 out of 5 by Not Impressed with Shippi from Hard to find these cartridges locally Our newest printer requires that the original go through the paper tray, which means things have to be torn out of a book, magazine, notebook, etc. Our oldest printer is the kind you can lay the original flat on the copier & press a button. No need to tear the article out of anything. 21 black ink cartridges are no longer carried by retailers in my area so I must order them from HP. Only issues I have with the product is when the ink runs out, I must wait on cartridges to arrive & they don't come in XL's. I could order more when I put the 2nd cartridge of my order in, but I don't remember to do so.

Looking to purchase a basic, cheap printer that uses the HP 21/22 Ink. I have a huge surplus of ink but old printer is broken. What printers use HP 21/22?

Thank you for your question! Unfortunately, no HP printers available currently for purchase use the HP 21/22 ink cartridges.

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.
