I have an HP Photosmart C3180 All-in-one. As I haven't had any need for color lately, when I last replaced ink, I only replaced the black cartridge. It didn't work, even when printing grayscale-only images, even when telling print-set-up grayscale-only.
To be precise: Black lines were black, but pale gray areas were an even paler yellow. I've just discoverd that the printer does the right thing with text from a pdf. The black ink cartridge is getting used, just not enough.
I used HPLIP, but it has been a while, so no details. Before remembering HPLIP, I'd tried to install the printer with just CUPS. It would not print. Using HPLIP, I got a rather long-named queue that would print. The other queue, the one with the name I wanted, will accept jobs, but never finish them.
Is there a way to tell my printer to use only the black ink cartridge. My test image is a handmade postscript file that only use setgray to set the color.
