Oki's latest C810n aims to break the mould, since it delivers support for A3 paper sizes at a price point starting on the right side of four figures - but also claims to be the smallest on the market. Measuring 485 x 579 x 345mm (WDH), the C810n is the most compact A3 laser we've seen, and print speed isn't a casualty since it can churn out A4.
