HP 343 - Print cartridge - 1 x colour (cyan, magenta, yellow) - 260 pages

What is HP ink?
Ink is much more than just coloured water; the unique, hi-tech formula for HP ink is designed to work with all the mechanical parts of the print cartridge, and the printer itself, to deliver high quality results across a wide range of papers, in a variety of environmental conditions.

More than just coloured water HP inks are full of features. View more detail

Why Original HP Inks?
It takes up to three years to develop new inks, so a huge amount of work goes into producing Original HP Inks, from the selection of superior ingredients to precision engineering of both the chemical formula of the ink and the high-performance ink cartridge components.

The print cartridge itself is the product of years of research and development and is much more than just an ink tank. The integrated print head on an HP cartridge includes an intelligent circuit that controls the hundreds of nozzles, each finer than a human hair, which deliver the ink onto the page. Each drop of ink is fired onto the page on the back of a tiny vapour blast of heat 7 times the intensity of the sun that lasts for just two millionths of a second; this energy blast exposes the ink drop to forces up to one million G’s. Some of the latest Original HP ink cartridges can deliver in excess of 29 million drops per second.

In many of HP’s home printers, over 50% of the printing technology is contained within the cartridge itself; which means every time you replace your Original HP Ink Cartridge you are installing a brand new print engine. Original HP Inks are developed in conjunction with HP papers to ensure maximum compatibility and performance. The result is the perfect balance of colour, permanence and reliability.

HP Ink Technology: pigment black and dye-based colour

Pigment Ink

HP uses pigment-based inks to deliver laser-sharp text, a strong black with superior fade and water-resistance on a variety of papers. Pigment inks are made up of relatively large molecules that are non-water soluble and sit on the surface of the paper. As a result, the ink is not absorbed by the paper and there is less bleed; resulting in cleaner edges and more efficient ink use.

Dye-based Ink

HP uses dye-based inks to deliver a broad spectrum of stunning, long-lasting colours. Dye-based inks are water soluble and are essential when intensity and range of colour is important. Used with high-gloss papers, dye-based inks provide a uniform finish with bright, vibrant colour reproduction and are perfect for photo printing and colour documents.

Original HP Inks vs. Refills
Given the degree of sophistication that goes into an Original HP Ink cartridge, it’s easy to see why refilled, second hand cartridges often suffer by comparison*. Common problems include a narrower colour range, poor fade resistance, lower page yield, banding, bleed and leakage.

Use of refilled ink cartridges can damage your printer, affecting the quality of your prints. If your printer is damaged as a result of using modified or refilled cartridges, it’s not covered by the HP warranty. Research has shown that one in five refilled cartridges fail prematurely or are dead on arrival*. For the best, long lasting results HP always recommends you use Original HP inks and paper.

Get More with HP
Page yield is an important measure of value for money when buying ink cartridges. Original HP ink cartridges produce up to 34%* more pages than compatible alternatives.

Remember, with Original HP Inks you’re not just getting value for money; you’re buying peace of mind.

HP Planet Partner Programme
HP offers a free cartridge recycling programme across 27 countries in Europe, the Middle East and Africa. To date, HP has recycled over 90 million kilos of ink and toner cartridges – that’s the equivalent of over 200 jumbo jets – and not one of them has ended up in landfill.

Best Choice Portfolio

HP offers a range of ink cartridges tailored to the way you print. To make things easier for you we’ve colour coded the packaging.

The standard blue ink cartridge is ideal for people who print low to moderate volumes, such as the occasional document, web page and photo.

The green XL cartridge is designed for people who print higher volumes. The page yield on an XL cartridge is up to five times that of the standard blue pack**

The red cartridges contain speciality inks, intended for advanced photo printing. Designed to work with high-quality HP photo papers they produce extra rich colours, ideal for photo printing, brochures and presentations.

HP Photo Paper
HP is the number one selling brand of inkjet photo paper*** and leads the world in image quality and fade resistance of inkjet photo prints. Original HP Inks and paper are specifically designed to work with HP printers to produce the best results for both home and office use.

HP Photo Paper, unlike plain paper, comprises multiple layers that are designed to deliver outstanding photo print quality, exceptional fade resistance, water-fastness and a vibrant range of colours. Plain paper, by contrast, consists of unsorted layers of cellulose and filler that expend when ink enters the paper and leads to “cockling” or uneven paper, affecting the quality of your photo prints.
