I'm not quite sure what you mean by "tint". Are you using a tint swatch?
If you make a new process swatch that's C-0, M-0, Y-0, K-75 it should print fine.
Depending on your actual printer, you might have to play its settings - things like saturation, etc. These are not normally available in the INDD print window. In that window, see if you have a Printer button. Click that to get to your printer's settings.
