Please take a look at our video relating to the Dell 5130 Colour Laser Printer:
WOW! This machine is super quick, built like a tank, has massive toners for long uninterrupted print runs and has low running costs. It's one of the largest A4 office printers on the market so may not be ideal for customers short on space, but if you have the room and the budget this machine is definately worth putting on your short list.
