      Genuine HP10 cartridges have never caused any problems.
      We normally buy several refills at once to feed our plotter. Next day delivery is always prompt and reliable - just what you need for running a busy drawing office, takes any uncertainty out of the process.
      We've used Cartridge Save for a couple of other printers in the office too as the price was good.

      Cartridge arrived quickly and was easy to fit. There appeared a little bit of leakage when it came out of the packet, but with a quick wipe all seems fine. The cartridge is not recognised by the HP K850 printer and one has to go through a set of key presses on the printer to get it accepted. The price and quality are fine.

      Product is working well so far.

      By big al on

      The cartridge was rejected by the printer, a HP Officejet Pro K850, when I inserted it. I had to adjust the settings to read non HP cartridge before the printer would work. Now I get a toner low message every time I print. The quality of the product appears to be very good. Other compatible cartridges I have used do not have this issue and hence the 4 stars.
    5. 100%

      By Debbie Kelly on

      My printer wasn't compatible with this cartridge which I found out for sure when the company sent me a second to try. People on the phone were extremely helpful and prompt. I was sent a genuine cartridge free of charge for the wait. I would highly recommend this company for example excellent customer service.

      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.

      Worked well after installation and informing the printer that it is not an HP cartridge. The latter point is not made clear and when you insert the cartridges the printer shows an error message, which says install a cartridge. The information is further confused by the instructions in the printer manual which says at the bottom of a page "if it is not an HP cartridge hold down the on/off switch and press the continue button" This does not work. On the next page in the manual it says "three times". I am sure that HP designed the manual to confuse operators. The cartridge installs when you hold the on/off button down and press the continue button three times. The price was very good and the quality from the HP k850dn is very good for every day work. For very high quality photo work I use a more modern printer.

      My printer wasn't compatible with this cartridge which I found out for sure when the company sent me a second to try. People on the phone were extremely helpful and prompt. I was sent a genuine cartridge free of charge for the wait. I would highly recommend this company for example excellent customer service.

      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.

    • 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.

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.

  • Hi, we recently purchased ink cartridges for the HP Officejet Pro K850 printer. However, it now appears that the ink tubes may be clogged through the lack of use. Before we buy a set of printheads we wondered if you supply any cleaning fluid or can recommend a way of cleaning the tubes and printheads? Thanks , Paul.

    HP Officejet Pro K850 printer cleaning

    Unfortunately, we don't sell cleaning fluid for printers, we only stock the replacement HP Officejet Pro K850 ink cartridges and printheads. We advise you to consult your Officejet Pro K850 printer manual for instructions on how to run a printhead cleaning cycle and then purchase some replacement Officejet Pro K850 printheads if you require them.

HP Officejet Pro K850 Printer Review

Expert review of the HP Officejet Pro K850 printer

Our Verdict:

Built for a small business, the HP Officejet Pro K850 is an affordable, wide-format printer that is network-ready, speedy, and versatile. While it's an attractive and sleek machine with excellent features for increasing productivity, it lags behind other models in terms of networking capabilities and media capacity. It can only handle 150 sheets, making it insufficient for an office printer.

Design

This 27.1-pound colour inkjet printer uses the 4 individual ink cartridge system, works with a wired parallel or USB interface, and uses PCL 3 language simulation. The HP Officejet Pro K850 has built-in 32MB RAM running and a Motorola ColdFire 4e 256 MHz processor, resulting in speeds of up to 24 ppm in monochrome and 21 ppm in colour when configured into draft mode. The sleek body has no visible buttons and an actual control panel.

Advantages

Users can enjoy more savings with the HP Officejet Pro K850 because of individual ink tanks and cheaper inks. High-resolution graphics can be printed at 4800x1200 dpi, and there is an optional automatic duplexer that saves time and paper. The HP Officejet Pro K850 can be integrated into a network with optional networking features, while the built-in Ethernet port makes it useful for at least 5 computers.

Disadvantages

One of the set-backs of this printer is its frame, which tends to attract dust according to some users. The HP Officejet Pro K850's paper feed has difficulty picking up paper. This can sometimes lead to paper jams, too. Some users complain about poor customer support and difficulty in setting up the HP Officejet Pro K850 in a network.
