The HP 300 ink cartridges serve several HP printers. Regardless of which you own, the OEM cartridges should always be the top choice. Using standard HP ink always delivers the best performance. The HP 300 series has a separate black and tri-colour cartridge that delivers cyan, magenta and yellow.
Standard HP 300 cartridges are sold separately or in a combo pack. The combo pack includes the black and tri-colour cartridge at a slightly lower price. You can choose to buy each cartridge separately and replace them as they run out, or plan ahead and buy both at the same time.
Those who print large volumes appreciate the existence of the HP 300XLs. These cartridges are also OEM, and offer a significant improvement in the print economy. There is both a black and tri-colour extra-large cartridge. Some vendors even offer an XL combo pack. Also, you can use a combination of one standard and one XL cartridge. Choose the set of cartridges that suits you best, and customise your printing experience.
