Combination color inkjet and laser image-printing device with dual paper-picking mechanism and method of implementing same

摘要

An image-printing device includes a dual paper-picking device that has two independent means of pulling sheets of paper or other print medium from a supply and feeding the same to the image-printing device. With two paper-picking means operating independently, two different paper transport paths can be operated. One path includes a laser print engine and prints monochromatic pages. The other path includes an inkjet print engine and prints color pages. The image-printing device firmware determines whether each page is a color or monochromatic page and formats the page accordingly for the appropriate print path.
