Main Features

General Features

  • Create documents that look professional with smooth, solid images, clear grayscales and consistent halftones; the Priport DD 4450 incorporates advanced ink control technology that distributes High Density Ink with precision and control.
  • Further enhance image quality with the Priport DD 4450’s Print Pressure Sensors, which automatically adjust for speed, temperature and humidity—key factors affecting print output.
  • Fine-tune documents—whether they’re text, a combination of text and photos, or handwritten originals—via User-Selectable Imaging Modes.
  • Reduce ink consumption while increasing ink yield per cartridge with a sophisticated ink control system that efficiently manages ink delivery.
  • Enjoy significantly diminished per-page costs thanks to print masters that yield a generous 4,000 prints—double the capacity of competitive digital duplicators.
  • Eliminate the need to produce costly and time-consuming originals on an inkjet printer prior to printing on the high-speed Priport DD 4450. Printing directly from your networked computer’s desktop is as easy as point and click.
  • Keep more work in-house and reduce expensive outsourcing when you use the Priport DD 4450.
  • Enjoy a simplified 4-line LCD Control Panel that mimics a typical copier control panel, which means everyone in your organization will quickly learn how to operate the system.
  • Connect directly to a workstation or network via the optional Type 4545A embedded PC controller.
  • Easily add colorful graphics, headlines and borders with a simple change of print cylinders.
  • The Priport DD 4450 is fully compliant with RoHS (Restriction of Hazardous Substances) and WEEE (Waste Electrical and Electronic Equipment).
  • Power consumption is relatively low compared to that of other high speed imaging devices.
