This is not supported in HPIJS 1.4. Use a newer HPIJS/HPLIP or the source code patch from Matthias Bunte. http://www.openprinting.org/download/printing/hpijs/ As the former patch for HPIJS 1.3 this patch applies to the DeskJet 6xx, 8xx, and most 9xx printers (and compatible multi-function devices) and lets black text being printed with only black ink and not with a mix of all inks. This way ink is saved and the quality gets better. Please test the patch. See installation instructions on http://www.openprinting.org/download/printing/hpijs/README.txt for instructions. Note that from the DeskJet 9xx series only the older-style models without hardware-internal color generation/dithering (HP DeskJet 930C, PSC 950, …) are affected. This patch is still in testing, please report results to the forum.
