      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.

      Worked immediately. I couldn't get the computer to recognise the CatridgeSave own-brand version whatever I tried, and it cost more in time and frustration than paying the extra to get the HP one. Fast delivery and cheaper than in the shops.

      Easy to use ordering system, plus you are able to re-order which is really quick and easily.

      Really good price - much cheaper than in the shops, but the same quality printing.

      Service is great - delivered the following day, which is just what you want when you are running low! They also send a postage paid envelope, so you can to recycle the used cartridges which I think is a brilliant idea,and I always use this.

      Recommended to friends ..... BRILLIANT!

        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.

      Worked immediately. I couldn't get the computer to recognise the CatridgeSave own-brand version whatever I tried, and it cost more in time and frustration than paying the extra to get the HP one. Fast delivery and cheaper than in the shops.

HP Deskjet 3720 Printer Review

Expert review of the HP Deskjet 3720 printer

Our Verdict:

Heralded as the world’s smallest all-in-one printer, the HP Deskjet 3720 boasts excellent print quality, as well as standalone copying and scanning capabilities. Incorporating a scroll feed scanner and digital copier, this ultra-compact machine uses Inkjet technology to create dazzling images and professional documents. Operated via wired connectivity or Wi-Fi, the printer is ideal for homes and small offices due to its small stature.

Design

Measuring approximately 142 x 403 x 177mm and weighing 2.33kg, the HP Deskjet 3720 can be connected via high-speed 2.0 USB or wirelessly through Wi-Fi and Apple AirPrint and is designed to be used with the HP ePrint app. The printer features an Icon LCD display, manual double-sided printing and a quiet mode, as well as a scroll feed scanner, a tray capacity of 60 sheets and duty cycle of 1,000 pages per month and the ability to scan to email via its app.

Advantages

Designed to be compact and visually exciting, the HP Deskjet 3720 will fit seamlessly into just about any home office space. In addition to its size, the printer features excellent print, copy and scan resolutions, with photo lab-quality images and documents produced quickly and efficiently. This all-in-one machine prints with a maximum resolution of 4800x1200 dpi and scans documents at a maximum resolution of 1200x1200 dpi. Up to 10 ppm can be printed in monochrome, or 8 ppm in colour and the scanner operates at a speed of 15 seconds per A4 page. The HP Deskjet 3720’s quiet mode means that documents can be printed from any room in the home with minimal disruption to other occupants.

Disadvantages

While the printer does have many shining qualities, its inability to print on both sides of a page without manual intervention is a flaw and the scanner is somewhat tricky to master the first few times it’s used. In addition, the scanner can only replicate one page at a time, reducing its speed and efficiency.
