The HP Deskjet 640 and 642c Inkjet Printers are each reliable and useful colour devices. Ensure that each page is as vibrant and sharp as the last with genuine HP consumables.
Our genuine HP Deskjet 640/642c Inkjet Printer Ink Cartridges are designed especially for devices in the 640 series and get the best possible results from them. Working smoothly and harmoniously from the moment they're installed, they preserve the longevity of their host device - ensuring that you get great results for longer. These results entail lasting, vibrant colours, sharp, crisp lines and beautifully rendered images that are great for professional and recreational purposes alike.
The cartridges are also very efficient. The high yields of the black cartridges, and the integrated 3-in-1 design of the coloured versions, ensure that your waste and downtime are kept to an absolute minimum. They go even further through their low operating temperatures, which reduce your energy costs and carbon emissions. Such value for money and environmental efficiency is very much absent in generic consumables. These wasteful, volatile products are not designed for printers in the HP Deskjet 640 range and are not covered by HP's warranty as a result.
Simply refer to the instructions provided to change your ink cartridges when necessary, ensuring that they are recycled afterwards. This will further minimise your environmental impact.
Printing up to six pages per minute at 600 x 300 dots per inch resolutions, the HP Deskjet 640 and 642c Inkjet Printers are each well-suited to small or home offices. They excel across a wide range of media types - including everything from envelopes and labels to transparencies and photo paper - and are particularly useful as a result. Such usefulness is reinforced by their compatibility with Mac and PC systems, as well as their paper handling.
