OKI C5250n
 

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.

I like my C5150N a lot; excellent in color quality and photo print from plain paper.
