I have the printer preferences set to print in black and white high quality grayscale, but I am only getting color output. My cartridges are low and I cannot print in color. Please help, thanks!
This is a function of your printer. You could change your image to grayscale, but most printer, unless they're designed to print b&w will use all the colored inks to create the "high quality" grayscale. The best you can probably do with your printer, which you didn't mention what type it is, is to set it to print with black ink only.
