Check the ink levels
Sometimes, the printer may not print black ink because it is low or empty. You can check the ink levels on the printer`s display, or by using the software that came with your printer. If the ink level is low, replace the cartridge or refill it according to the manufacturer`s instructions.
Move your cursor and click on “Properties” and then the “Color” option. Here, choose the option “Print in Grayscale” by just hitting on its checkbox.
Check Cables and Printer USB Ports
Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.
Why is CMYK black not black? If you use 100% K to create a black in CMYK color mode, you`ll end up with a deep gray, not a true black. To get rich black, you need to add the right amount of all four colors: cyan, magenta, yellow, and black.
The answer is yes, your printer uses a bit of all colors (black, cyan, magenta, yellow) every time it prints. According to HP Support, “[our] printers are designed in such a way that it also uses color inks while printing in black to form a perfect black. This is called as K-fortification in printer terms.

Ghost prints happen when the drum or fuser unit within your printer become faulty. Because a fault with this element won`t heat the particles of the toner to a high enough temperature, the marks being made on the paper are much lighter in colour and appear more faded than typical documents.
Many printer models require at least some ink in all cartridges to keep printing. However, if you`re lucky, your software may allow you to squeeze out the rest of your color ink without using black.
If your HP printer not printing black ink correctly, here`s what you should do. Using non-genuine ink cartridges. Printheads that have become clogged. Ink cartridges that are defective or empty.
If your printer is having issues printing black ink, the black ink might be low, and the printer might be running in backup mode. Check estimated ink levels to see if any ink cartridges are critically low or empty.
