how do I use only black ink?

[Michael Hennebry <hennebry@xxxxxxxxxxxxxxxxxxxxx>]

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.
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.
