HP DesignJet 650C 300 300 4 Cartridges http://www.hp.com/designjet/ B dnj650c Large-format inkjet printer.<p> 600 dpi in grayscale, only 300 dpi in color.<p> Works "almost" - RGB data are sent to the plotter. The CMYK mode of the "B"-Models and the 75x Series is not supported. Images are somewhat "greenish"; gray is composed of CMY. Nice for really LARGE printouts ... (ISO A0).<p>
