Refilled Twin Pack of HP 338 and HP 343 Ink Cartridges

Will this cartridge work in my HP printer?

Use our 'Check this ink fits your printer' box at the top of this page to confirm this cartridge is suitable for your printer model. In most cases the model number is written on the front of your printer.

Note: These cartridges will only work in printers purchased in the UK and Europe. Printers purchased outside of these zones will have different coding and electronics.

How much ink is in a HP Refilled cartridge?

We don't advise on the number of millilitres, as not every cartridge prints using the same droplet size, so two cartridges for two different printers may both have 5ml of ink, but one will print more than the other. Instead, more accurately, the industry standard is based on printing 5% of an A4 page.

How many pages will this HP Refilled cartridge print?

This is known as page yield. The number of pages you'll be able to print depends on the cartridge you purchase and the kind of printing you do. The page yields shown higher up the page are based on printing 5% of the area on an A4 page.

Will this cartridge work alongside HP Instant Ink cartridges?

No, you aren't able to use other cartridges alongside your HP Instant ink ones. Cartridges in the Instant Ink program have different coding, so whilst enrolled, you are locked into their service and must use their cartridges. Read our blog to learn more about HP Instant Ink.

What is a refill cartridge?

These are refilled HP cartridges which means they have been used once previously before being reconditioned and refilled with ink, making them a more environmentally friendly option that still provides the print quality you need.

Do the cartridges display ink levels?

As these are reconditioned HP cartridges, there is a small chance that ink levels will show the last level status. This does not affect the functioning of the cartridge, but should you have any queries, do not hesitate to contact us, or look at our Ink Reader Level Guide, should you need help.

Are these cartridges easy to install?

Yes, these cartridges are just as easy to install as the originals. Make sure the required clips have been taken off, along with the clear (usually blue) tape that covers the metal panel on the underneath of the cartridge, and then slot the cartridge into your printer. Do NOT remove the brown tape that is connected to the contact chip. See our Refill Installation Guide for more details.
