HP 728 300-ml Magenta cartridge

This genuine HP 728 cartridge supplies 300 ml of magenta dye-based ink for HP DesignJet T730 and T830 printers. It is built for design and engineering workgroups that produce CAD drawings and general-purpose prints. The single-pack format fits directly into the printer's ink system.

Capacity and headroom

The 300-ml volume supports extended unattended printing runs, reducing the frequency of cartridge changes during high-output periods. Ink drop size of 6 pl helps deliver crisp lines on technical documents. Once the 300 ml is depleted the cartridge must be replaced; there is no larger single-unit option in this series.

Upgrade context

This cartridge replaces the 40-ml size in the same HP 728 series when teams need longer intervals between swaps. The jump is worthwhile when print volumes make frequent 40-ml changes disruptive. It is not for users whose output stays low enough that the smaller cartridge lasts weeks.
