      By HP Black & Tricolour Inks on

      As usual arrived very.promptly & in good condition.
      The HP inks are so reliable for use in my Officejet 7210 Printer. I find them of excellent quality. Being a senior citizen I do however find the inks are very costly. I did once try inks of a lower cost, but nearly ruined my printer!!!
      I would recommend the company to others for the points mentioned above.

      3-year warranty on our own-brand cartridges
      We are proud of our own-brand cartridges, so we’ve made trying them a no-brainer. If within three years of purchase you have any problem whatsoever, we’ll happily offer either a replacement or a refund.
      Returning items is easy—it takes just a few minutes. But our return rate is very low, so you’ll be unlikely to need it.
      We are confident that no other own-brand cartridges are better than ours. They produce vibrant prints with accurate colour densities and dark blacks—and their page yields are as good as the genuines, if not better. Give them a try, and see why our customers love them.
      Our own-brand cartridges are incredibly reliable for three reasons:
      1. We are the UK’s biggest seller of own-brand cartridges, and we have invested a lot in optimising them.
      2. We are dedicated to quality. Every own-brand cartridge is performance-tested before it leaves the factory.
      3. We constantly monitor customer feedback, and quickly resolve any issues.
    • Printer protection guarantee
      Our cartridges won't damage your printer—guaranteed
      Some people worry that own-brand cartridges might damage their printers. We know from experience that ours don’t.
      To reassure you, we guarantee that we’ll repair or replace your printer—for free—in the unlikely event that it gets damaged by an own-brand cartridge. This is regardless of how old your printer is. We can afford to offer this because problems are almost unheard of.
      Some people whose printers are less than a year old worry that an own-brand cartridge might invalidate the manufacturer’s warranty. This isn’t true. By law, the manufacturers aren’t allowed to invalidate your warranty if you use own-brand cartridges. If something does go wrong, and our own-brand cartridges are to blame, we’ll take over the manufacturer’s warranty, offer you phone support and repair or replace your printer if needed.

      In summary, there’s zero risk in using our own-brand cartridges.

      I purchased this for a HP Photosmart 7850 that my grandson needed to print his school homework during this present lockdown.
      The cartridges arrived, next day as advertised and were fitted and running in a matter of minutes. These are great value cartridges and the service I would recommend to anyone that needs printer cartridges.

HP Deskjet 6840 Printer Review

Expert review of the HP Deskjet 6840 printer

Our Verdict:

A futuristic design and compact body makes the HP Deskjet 6840 an attractive addition to a modern home or compact office with a small network of computers. It comes with additional features like an extra paper tray and a duplexer. Some aspects of its design are clumsy and inefficient, though, and the required consumables are one the expensive side.

Design

This printer is among HP's high-end products and boasts fast print speeds and easy networking with up to 5 computers. The HP Deskjet 6840 can be hooked up with a USB 2.0 cable or via Ethernet, and allows wireless printing with WiFi and PictBridge interfaces. The printer is only 13.2 pounds. All the controls are easily accessible on the front panel, and the print status is displayed on the LCD screen. HP has equipped the Deskjet 6840 with a badly-designed output tray that is bulky and outdated, according to many users.

Advantages

The print quality of the HP Deskjet 6840 is consistently good. The Ethernet and WiFi capabilities of the printer allow ease in connectivity and faster output. The additional duplexer and paper tray adds to the efficiency, especially in accomplishing multiple print jobs.

Disadvantages

Despite the cutting-edge design, the HP Deskjet 6840 is slower compared to other inkjet printers from competitors. Draft speed is 30ppm, but 'normal' to 'best' monochrome speed is only between 2ppm to 9.8ppm. Colour printing is also slow at 5.7ppm in 'normal' mode and 2ppm in 'best' mode. Also, the paper tray is prone to jams and could use an upgrade. Some users also report difficulties networking difficulties with the HP Deskjet 6840.
