Genuine OEM HP DesignJet T2600 PostScript 36In. Ink and Supplies
The DesignJet T2600 PostScript uses HP 730 ink and a separate B3P06A printhead. Ink cartridges supply the ink; the printhead puts it on paper. That makes the printhead a different purchase from filling one of the printer's low ink colors.
At Toner Buzz, you'll find genuine HP 730 individual inks in two sizes per color and the B3P06A printhead. Both sizes of a given color serve the same cartridge position. Choose the larger volume when you want more ink in that position before the next cartridge change.
