Excerpt: A workgroup colour laser printer ticks all the right boxes in most offices. It can print day-to-day mono text at good speed, but can also add colour graphics or photo images when needed. Brother's HL4070CDW also adds wireless connection and duplex to the mix. This is a big, square-cut machine, though with curved vertical edges front and rear to relieve the functional looks. Coloured in cream, dark grey, slate and with silver highlights, it looks clean and modern.
