TrustedReviews posted a review of the OKI C5250n colour LED printer

Colour laser printers fall into two design categories. There are carousel machines, which move the toner and drum cartridges round a carousel to apply each colour, and then there’s the inline design, where all four colours are applied in turn, in a single pass. The C5250n is an inline machine, so it’s potentially quite quick, but is also physically deep, in comparison with the more boxy HP and Epson devices.
