HP 712M 38ML INTRO CONTRACT BLK INK CRTG

HP 712M 38 ml Intro Contract Black Ink Cartridge (3ED66A) is a black ink cartridge for compatible HP DesignJet printing. Its introductory contract designation distinguishes it from other HP 712 black cartridges, while the 38 ml fill gives the exact capacity of this variant.

The distributor lists it for the HP DesignJet Studio 36-in printer and associates it with the T230, T250, T650 and Studio families. It is intended to supply black ink for these DesignJet printers, supporting routine printing with the specified cartridge type.

This is the 38 ml introductory contract version, rather than the other HP 712 black cartridge variants shown alongside it.
