HP 78 Tri-color Original Ink Cartridge
Description
The HP 78 Tri-color Original Ink Cartridge is a genuine HP colour ink cartridge designed for a wide range of legacy HP DeskJet, OfficeJet, Photosmart, Color Copier and related inkjet printers. The cartridge combines Cyan, Magenta and Yellow inks in a single integrated tri-color cartridge, allowing compatible printers to produce colourful documents, graphics, photographs, presentations and everyday home or office prints. The standard HP 78 cartridge, commonly identified by product number C6578D or regional variant C6578DA, contains approximately 19 ml of tri-color ink. HP also produced a larger 38 ml HP 78 cartridge under product number C6578A. Designed together with compatible HP inkjet printers, the HP 78 cartridge includes an integrated printhead and ink supply, meaning the printhead is replaced together with the cartridge. This can help restore reliable colour output when a new cartridge is installed. The HP 78 is used alongside compatible Black cartridges such as HP 45 or HP 15 depending on the printer model. Because the HP 78 family and its compatible printers are now legacy products, customers should carefully confirm their exact printer model and cartridge number before purchasing.
