Iirc even when printing black-and-white and specifically not choosing to print in color, the printer still uses some of the other colors to get a more “true” black. So in order to legit print in just black-and-white, you want a monochrome printer - otherwise, the printer will keep using smaller amounts of other ink for the black colors.
You’re close. True black, like black text, will use black only. But any slightly off shade of black will combine all other colors to make some kind of grey because if you’re using a color printer grey isn’t just “less black”. You can fix this by either setting your color printer to black only or grayscale, or like you said getting a monochromatic laser printer.
