Epson WorkForce Pro WF-4720DWF The Epson WorkForce Pro WF 4720DWF is a fast cost effective four in one colour printer for the office. It combines easy to use functionality with high capacity input trays and a high-speed printing engine to provide a powerful office printer that is suitable for both small and medium-sized workgroups. High-performance 4-in-1 printing for the home or office The Epson WorkForce Pro WF 4720DWF uses Epson's PrecisionCore technology which provides industry leading high definition image reproduction at super high speed. PrecisionCore printheads have up to three times more nozzle density than conventional printheads with each dot printed just 40 microns across. That helps to create sharper text and finer lines improving the definition on images and removing fuzzy lines from the edge of text.PrecisionCore printheads are also recognised as one of the fastest inkjet printheads in the world with each element firing at nearly 50000 times a second. This helps speed up the printing process allowing full-colour images to be printed at speeds up to 20ppm and making the WorkForce Pro WF 4720DWF one of the fastest full-colour inkjet printers on the market. Extremely low running costs The Epson WorkForce Pro WF 4720DWF uses Epson's DURABrite Ultra ink which offers great value compared to other inks and is specially formulated to work with the PrecisionCore printhead. DURABrite Ultra ink is available in XL cartridges which allow you to print up to 2600 black and 1900 colour pages assuming 5% page coverage. By using XL cartridges you can save up to 20% compared to using a standard sized cartridge. Freedom to print from anywhere The 4720DWF also gives you the freedom to print from anywhere in the office thanks to its Wi-Fi connectivity options. This can be used to connect to the office Wi-Fi network or to print directly to the printer using Wi-Fi Direct from wireless-enabled devices such as laptops and smartphones.
