Welcome to the HP Forums, this is a great location to get assistance! I read your post and see that you want to print in black. I would like to help you resolve this issue.
However, I will need a few details to provide an accurate solution,
When did this issue start?
Did you do any hardware or software changes?
How is the printer connected to computer, wired or wireless?
Meanwhile
Check the print settings
In the software application you are trying to print from, click File, and then click Print.
The Print window opens.
Open the Properties dialog box.
Depending on the software application, the button might be Properties, Options, Printer Setup, Printer, or Preferences.
Depending on your print job, you might consider modifying the following settings:
Paper Type: If you are printing on photo paper, select the type of photo paper you are attempting to print on.
Print Quality: If you are dissatisfied with the quality of your printouts, increase the print quality. To print more quickly, decrease the print quality. These options typically include Best, Normal, and Draft modes.
Paper Size: If you are printing on a different size of paper than you normally print on, select the correct paper size.
Black and White: If you want to print in black and white only, select the grayscale option.
After selecting the print settings, click OK to apply the settings, and then click Print.

Let me know how it goes.
Cheers.
