Problem is that system-config-printer assigns the Gutenprint driver to this printer. The Gutenprint driver is a monochrome PCL 5e driver. The printer needs a color driver, PCL 5c or PostScript. I have changed system-config-printer's prioritization for PostScript/PCL printers without manufacturer-supplied PPD now, so that PostScript and HPIJS are preferred and not Gutenprint. The Xerox Phaser printers are used in PostScript mode then.
