      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.

      It was very easy to find and order my cartridges on the web site, I had a problem with the initial order - no fault of cartridge save - the staff especially Kirsty could not have been more helpful. Very impressed, excellent customer service.
      The HP 304 XL cartridge was very reasonably priced, prints perfectly and I would definitely recommend cartridge save.

        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.

HP Deskjet 3730 Printer Review

Expert review of the HP Deskjet 3730 printer

Our Verdict:

The HP Deskjet 3730 is a typical all-in-one printer that also offers standalone scanning and copying capabilities. Connected via high-speed USB or a wireless network, the printer operates thermal Inkjet printing using two cartridges, one black and one colour. Compact enough to be used in a small home office or for personal use, the printer’s simple colour scheme will seamlessly fit into any room, while its ability to complete jobs quickly and efficiently make it a valuable addition to any workspace.

Design

Measuring approximately 141 x 403 x 177mm, not accounting for its input tray when fully extended and weighing 2.33kg, the HP Deskjet 3730 is capable of printing, copying and scanning. It features an Icon LCD display for easy print management and can complete a duty cycle of up to 1,000 impressions per month. This machine can be connected via a high-speed USB device, or by using a wireless network. It is compatible with a range of mobile devices, supporting Apple AirPrint, the HP ePrint app and Mopria Print Service, among others. The HP Deskjet 3730 can create standard prints and images, as well as envelopes, labels, cards and documents of custom sizes.

Advantages

As well as being compact and, therefore, ideal for home office use, the HP Deskjet 3730 can create beautiful documents and images. It has a maximum speed of up to 8 ppm for monochrome and 5.5 ppm for colour and will hold up to 60 sheets of standard A4 paper in the input tray; the output tray holds 25 sheets. The printer’s maximum resolution is 1200x1200 dpi in monochrome and 4800x1200 in colour, or 600x600 pixels per inch for the scanning function. In terms of copying, the machine is capable of replicating 4 ppm in black, or 2.5 ppm in colour.

Disadvantages

While the HP Deskjet 3730 can print double sided, this must be done manually; as a result, larger jobs will take longer to complete.
