Welcome to HP Forums. This is a great place to get support, find answers and tips to your technical queries.

I got to know from your post that you are not able to print in black. I'll be glad to help you out. However, for an accurate solution, I would need more details:

Are you able to copy document in black?

Could you also print a test page and let me know if it has black in it. In order to print the page, press and hold the Power button , and then press the Cancel button  then let go of the Cancel button and then the Power button.

Let me know!

Hi I’ve tried doing a copy in black ink and printing a test page as you suggested but still no black ink only tri-colour. I’ve removed the black cartridge and wiped the contacts on the bottom of the cartridge but still no success with black ink I’m afraid.

Thanks! Power resetting the printer and then performing an automated cartridge cleaning resolve the issue, let's try these steps:

1) Make sure this printer is plugged into a direct wall, not a surge protector

2) Remove all of your ink cartridges from the printer and close the door

3) Remove the power cord from the back of the printer (Do no press the power button)

4) Plug the power cord back into the printer

5) Wait for the printer to turn on completely, then install the ink cartridges.

6) On you Mac, click the Apple menu, and then click System Preferences.

7) Depending on your version of OS X, click Print & Scan or Printers & Scanners.

😎 In the Print & Scan or Printers & Scanners window, select your printer, and then click Options & Supplies.

9) Click Utility, and then click Open Printer Utility.

10) Click Clean Printheads , and then click Clean. Click Cleaning Level 2 to continue the next level of cleaning.

11) Click Align  on the HP Utility.

12) On the Align Print Cartridges window, click Align.

Let me know how it goes!

I have the exact same issue on PhotoSmart 7520.  I followed all the steps above and black is still not printing despite a new cartridge. I am running macOS 10.14.5 on a 2017 MacBook Pro 15 inch. The HP driver version is 2.  I also tried using HP Easy Start to uninstall and the reinstall the HP software. It says I'm ready to print.

Can you help me?

HP Recommended

Opps. Typo. that should be 7920.

I had the same problem:  after replacing the black ink cartridge the printer still would not print black ink.  Here's a laugh, I had forgotten to remove the protective tape from the print head of the new cartridge!!
