HP DesignJet T850 36” Printer (2Y9H0A)
Professional A0 large-format printer for CAD, construction, and technical drawings
The HP DesignJet T850 36-inch printer is a professional large-format solution designed for architects, engineers, and construction teams who need durable, accurate, and reliable A0 / A1 printing. Built for medium-volume technical environments, the T850 delivers fast output, excellent line accuracy, and long-lasting print quality using HP pigment-based inks.
*Please note* This model is the printer-only version. See the T850 36″ multifunction variant for scan and copy workflows.
High-quality A0 / 36” printing
The HP DesignJet T850 produces crisp CAD drawings, technical schematics, and site plans with consistent line accuracy and sharp detail. Supporting media widths up to 36-inches (914 mm) and long roll printing, it’s ideal for A0, A1, and custom-length drawings, such as those used in civil engineering projects.
Pigment-based HP inks ensure prints are water-resistant, fade-resistant, and suitable for site use, making them ideal for construction environments and long-term reference documents.
Reliable media handling for busy teams
Designed to support professional workflows, the T850 offers flexible media handling to keep productivity high:
- Roll and sheet printing for mixed media, or mixed size jobs
- Integrated fabric basket, upgradeable to A0, A1, and A2 sheet stacking
- Supports 50m roll lengths for continuous drawings
- Optional accessories available to expand workflow flexibility
This makes the printer well suited to offices producing plans, drawings, and technical documents throughout the day.
A pigment ink system built for durability
The HP DesignJet T850 uses HP 738 pigment ink cartridges, available in 130ml and 300ml sizes. This system delivers:
- Long-lasting, water-resistant prints
- Excellent line clarity for CAD and GIS drawings
- Strong colour performance for technical graphics
- Improved value per millilitre for regular use
- Wider selection of medias, including (but not limited to) vinyls, polyprops, and self-adhesive

The T850 integrates seamlessly into modern office and studio environments with smart software and connectivity:
- HP Click for fast, one-click PDF printing
