The HP DesignJet T850 is a large-format printer in the business segment class, specifically designed for use in professional environments such as architectural offices, engineering offices, or graphic design studios. With a maximum print size of A0 (841 x 1189 mm) and a print resolution of 2400 x 1200 DPI, it offers high precision and detail accuracy for technical drawings, plans, presentations, and creative print products. The print technology is based on Thermal Inkjet, whereby ink is applied to the medium by thermal heating. This ensures even color distribution and high print quality, especially for color prints. The printer features four print cartridges in the colors Cyan, Matte Black, Magenta, and Yellow, enabling a broad color palette. Print speed is 90 pages per hour at normal quality and A1 format, which is sufficient for professional use.

Applications

The HP DesignJet T850 is designed for use in offices and workspaces where large, high-quality prints are required. It is particularly suitable for creating construction plans, technical drawings, architectural visualizations, graphics, and presentation materials. Support for various ISO A formats (A0 to A4) as well as custom media sizes (input tray: 210 x 279 to 305 x 457 mm; manual feed: 210 x 279 to 914 x 1676 mm) enables flexible use. The maximum media width is 914 mm, and the printer can process rolls up to a diameter of 10 cm and a weight of 6.2 kg (rear roll). The recommended media thickness is between 60 and 280 g/m², and the device is also compatible with materials such as coated paper, photo paper, bond paper, matte paper, banners, and satin paper. The integrated cut sheet function allows automatic cutting of printed sheets, improving workflow efficiency.

Functions and Equipment in Detail

The printer supports various page description languages, including HP-GL/2, TIFF, JPEG, HP-RTL, CALS G4, and URF, facilitating integration into existing CAD and graphic systems. The line accuracy of ±0.1% ensures precise line guidance, which is especially important for technical drawings. The integrated HP dynamic security ensures that only HP print cartridges with chips or electronic circuits can be used. This feature is maintained through regular firmware updates. Memory capacity is 1024 MB, sufficient to buffer print jobs and optimize processing speed.

Technology Explained Simply

The Thermal Inkjet print technology works by selectively heating the ink in the printhead channels, causing small ink droplets to be deposited onto the paper. This method enables high resolution and color accuracy. The maximum resolution of 2400 x 1200 DPI ensures sharp details and smooth color gradients. Power supply is via voltage 100 to 240 V at a frequency of 50/60 Hz, enabling worldwide use. In standby mode, the printer consumes 2.5 W, and in the off state, only 0.2 W, highlighting its energy efficiency. Certification according to ENERGY STAR confirms environmentally friendly energy usage.

Compatibility and Accessories

The HP DesignJet T850 features Ethernet/LAN with a data transfer rate of 1000 Mbit/s as well as WLAN functionality, enabling flexible network integration. Support for Apple AirPrint allows mobile printing from iOS devices. Printing can also be done directly via USB. The software environment includes the HP Click App, the HP Click Driver for Windows 11, and the HP App for Windows, macOS, Android, and iOS, simplifying operation and control of the device across various platforms.
