Why won't my printer 8020 print blue?

[SLeepy7]

Prints all other colors but blue and obviously green.

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

The printhead could be clogged, and you might need to clean the printhead several times to restore print quality. 

1. On the printer control panel, swipe down to open the Dashboard, and then touch the Setup icon .

2. Swipe up on the display, and then touch Printer Maintenance.

3. Touch Clean Printhead, and then touch Continue.

   A test page prints.

   

4. Examine the test page.

   • If the print quality is unacceptable, touch Clean Again to continue the next level of cleaning. If necessary, repeat these steps for the third cleaning cycle.

     NOTE: If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes before you perform all three levels of cleaning again.

   • If the print quality is acceptable, touch Done.

Hope this helps! Keep me posted for further assistance.
