Epson has unveiled its new WorkForce 520 all-in-one printer, scanner, copier and fax machine. This machine claims to be the fastest offering in its category, offering 15 ppm (pages per minute) in black and 5 ppm in color. The benefits of the built-in Wi-Fi radio become obvious when you want to get some printing done and your PC is further away. The 30-page automatic document feeder (ADF) should also go some way to making your life in the office easier. If you need to scan documents, it’s able to scan directly to email and PDF at up to 2,400 DPI resolution. The use of five individual ink cartridges mean you only need to replace the cartridge that is empty, instead of a set of colors, helping you shave some costs.
