The Epson AcuLaser C4000 and Epson AcuLaser C4100provide businesses with high performance colour and monochrome printing solutions. They add crucial colour to your business, while producing high quality monochrome output at lower costs than many monochrome-only printers - and they are just as easy to operate. So now there´s no reason to buy two printers because perfect monochrome and colour solutions are available in one.
