The HP 15 black and HP 23 colour ink cartridges are a pair of inkjet printer cartridges, which are used together in several Hewlett Packard printers. Using three coloured ink cartridges, with black, provides traditional four colour printing, which is fine for most business use, but is not as good as five or more colours when printing photographs with inkjet ink. As inks are used at different rates, having a combined three-colour ink cartridge is less economical than having individual ink cartridges.
We can supply two types of printer cartridge in this range: HP original inkjet cartridges and remanufactured (recycled) ink cartridges. We also supply InkTec ink refill kits and bulk ink for these cartridges. We do not supply compatible cartridges in these types.
If you are looking for cheap ink, we recommend that you look at the cost of refilling your own cartridges.
