Hi @nkhadvisors,


 I'd like to help!


To better assist you - 


1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or devices? 


While you respond to that, let's print a Print Quality Diagnostic page -

  1. Load plain white paper in the input tray.

  2. From the printer control panel, open the Setup  menu.

  3. Open the Reports or Tools menu.

  4. Touch Print Quality Report.

Post the Print Quality Diagnostic page here so we can help you further. 


You may also refer to this document with steps to fix " Print Quality Issues" issue applicable for your printer -  Print Quality Issues


 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 


Hope this helps! Keep me posted.

Hi Team,


All procedures attempted,  several times. Please see attached output from Diagnostic Page


Here is what I see;.  

When gray scale is turned off, no colors appears,  The fonts or background that are set with color,  print out with no color and appear as blank spaces in the output.


When gray scale is turned on, the green and blue text appear in grayscales.   Red, blue text, and yellow background have no color .


Black is fine in all cases


I look forward to your response and next steps.
