Questions about this item

Does the HP 3ED71A cartridge ship alone or with extra printheads?

The box contains only the 80 ml black pigment cartridge; printheads and maintenance items are sold separately.

Should I choose the 80 ml black cartridge or a larger capacity for my DesignJet T650?

The 712 series is offered in this 80 ml size; no higher-capacity black cartridge is listed for the T650.

What does the 31 % line-accuracy claim mean for everyday CAD prints on my T230?

Internal testing showed up to 31 % straighter 1-pixel lines versus a competing printer in fast mode on plain paper.
