Description

Pay Less for Your HP21XL Ink Cartridge

The HP 21 ink cartridge is probably one of the most popular and best selling printer cartridges on the market, since it's compatible with so many HP DeskJet, OfficeJet and PSC printers. It's reliable, easy to install and produces brilliant results. It has one flaw however: it doesn't hold as much ink as it could. This where the black HP21XL ink cartridge comes to the rescue - it's a high capacity version so you can print even more of your documents and photos with the same reliable and high quality. Also known as the HP C9351CE, the HP 21XL ink cartridge produces sharp and crisp blacks print after print, and because the HP 21XL cartridge uses HP's patented ink formula, it's super resistant to fade too.

Free Delivery on all HP 21XL Ink

Buying online can sometimes be a bit worrying - after all, how do you know how credible an online company is? We are proud to have an award-winning customer service team and to further reassure you we also offer a full money back guarantee on all our HP21XL ink cartridges.

  • What's the difference between a HP21 and a HP21XL printer cartridge?

    HP 21 and 21XL ink cartridges

    The HP 21XL cartridge is filled to a higher capacity and should last you at least twice as long as a standard capacity cartridge.

  • What's the difference between HP21XL and HP54 black ink cartridges for the Deskjet F4180?

    Black HP ink cartridges

    The HP Deskjet F4180 printer requires a HP 21, or a HP 21XL black ink cartridge if it is a printer purchased in the UK. The HP 54 black ink cartridge is a different product entirely and will not work in the Deskjet F4180 printer.

    Please contact a member of our freephone support staff if you require any assistance ordering the correct cartridge for your HP printer.

    Cartridge Save provide a very efficient service . They are helpful and reliable . My most recent order arrived the next day . I recommend them to all my friends who want cartridges.

  • By John Hall on 8 Aug 2016

    I always use HP cartridges with my HP printer as they always work ok and provide good quality printing. Cartridge Save provide excellent service and at a competitive price.

    very good service

  • By Sue on 17 May 2016

    Ink cartridges arrived the next day so no delay for using my HP printer. Prices very good and print is excellent

  • By Sylvia Denison on 12 May 2016

    Genuine product and very pleased with the speed of the order. Great that it goes through the letter box and I don't have to sign.

  • By Neil Harrington on 24 Feb 2016

    Cartridge works very well and the service is fast and efficient.

  • By DAVID WIGHT on 4 Feb 2016

    GIVES PERFECT COPIES EVERYTIME HIGHLY RECOMMEND

  • By Sylvia Denison on 17 Jan 2016

    The price of the HP Cartridge was very good especially as it is a genuine brand having previously had problems when I used alternative type. The delivery was excellent it was with us the next day. Will definitely use Cartridge Save again.

  • By Alex on 8 Jan 2016

    Good price, works very reliably and a long time.

  • By Ken on 26 Dec 2015

    These cartridges always work well and I see no reason to buy anything else. This high capacity one is the one to go for even if you only need a new one as infrequently as once a year. If you can do without one for a day or two then from Cartridge Save you can order when your old one dies!

  • By Dave on 12 Nov 2015

    This product lasts longer than the normal sized cartridges and gives a good performance.
