Genuine HP 712 Magenta Ink Cartridge

The HP 712 3ED68A is a genuine 29 ml magenta ink cartridge designed for HP DesignJet large-format printers. It uses dye-based ink to produce bright, distinguishable colours on technical drawings, maps and plans. The cartridge supports reliable printhead performance and helps maintain the printer's warranty coverage. It is built for professionals who need consistent output on plain and coated media.

Ideal for DesignJet T210, T230, T250.

This cartridge suits architects, engineers and GIS specialists who print line work, renderings and colour-coded plans on the listed DesignJet models. It is not for buyers who need pigment-based inks for outdoor signage or fine-art reproduction requiring archival pigment longevity. Offices using non-HP large-format plotters or printers outside the compatible series should look elsewhere.

29 ml capacity for everyday plotting volumes

The 29 ml fill handles routine CAD, GIS and presentation printing with consistent line accuracy and colour density. It comfortably covers daily check plots, client reviews and internal mark-ups. High-volume production environments running continuous roll feeds will exhaust the cartridge more quickly and should plan for frequent replacements.
