Why Is My HP Officejet Pro 6970 Black Ink Not Printing?

Whenever I try to print some docs, my HP Officejet Pro 6970 printer not printing the black ink properly. I don’t know what is wrong with my printer. It always put me in an idle state. I need to print right now, I need to present my project today in my office. Please help me as soon as possible.

Thank you, Misses, for sharing the printing issue. It happens because of improper cartridge alignment done during the printer setup. It also happens because of the low ink levels, outdated drivers, improper paper settings, etc.
