Genuine OEM HP DesignJet T2600dr PostScript 36In. Ink and Supplies
HP 730 cartridges for the DesignJet T2600dr PostScript offer two volumes of each ink color. The larger version holds more ink for the same slot, rather than adding another color. The separate B3P06A printhead handles ink delivery onto the paper.
Toner Buzz carries genuine HP 730 individual inks in both sizes, plus the B3P06A printhead for this model. Choose the cartridge color first and its volume second. Keep the printhead purchase for printhead maintenance; it isn't a substitute for adding ink to a low cartridge position.
