A duplex color printer includes a body defining a plurality of docking bays in which respective color ink cartridges can be docked in a releasable manner. A pair of opposed print engines is mounted within the body and a substantially straight print media path is defined there-between. Each print engine includes at least one printhead coupled in fluid communication to the docked ink cartridges and is configured to eject the ink. A pair of print media trays is mounted to either side of the body and each contains print media. A print media feed arrangement is configured to feed print media from one of the trays, along the straight path during printing and into the other one of the trays. The straight print media path enables high speed printing.
