Four-pack replacement for HP 21

This set contains four LD Products remanufactured black ink cartridges that replace the HP 21 C9351AN model. Each cartridge uses dye-based ink and delivers an approximate yield of 190 pages. The product is sold new and is intended for home or small-office printers that accept the HP 21 cartridge.

Check printer model before ordering

Verify that your printer appears in the supported list, which includes numerous DeskJet, OfficeJet, Fax and PSC models such as the DeskJet 3910, F2110, F300, F335 and OfficeJet 4315. The cartridges are not made by HP and will not fit printers that require a different cartridge number.

Fits straight into the cartridge slot

Installation requires no extra tools or adapters; the cartridge seats directly in the existing carriage. Using remanufactured units frees budget for paper or other supplies while keeping the printer operational for everyday black-and-white documents.

Questions about this item

What comes in the LD Products HP 21 4-pack and do I need anything else to start printing?

The box contains four remanufactured black ink cartridges that replace HP 21 C9351AN. No extra parts are required; install them directly into a compatible printer.

Should I choose the 4-pack or buy single cartridges for my HP DeskJet 3940?

The 4-pack gives you four cartridges at once, each rated for about 190 pages. Buying singles works if you only need one replacement now.

What does the 190-page yield mean for everyday printing on my HP OfficeJet 4315?

At standard 5 % coverage each cartridge prints roughly 190 pages. Heavy graphics or photos will reduce that number; plain text may stretch it slightly.
