      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.

      If your printer is less than one year old, your manufacturer’s warranty won’t be affected by using our cartridges (this is the law). However, in the unlikely event that our own brand products are to blame, we will take over the manufacturer’s warranty offering phone support and, if needed, repair or replace your printer.

      This means there is absolutely no risk in giving Cartridge Save own brand cartridges a try.

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.
