Welcome to HP Community

I have gone through your Post and would like to help

Do you have adequate amount of ink left in all the cartridges?

Use HP Printer Assistant to print a Print Quality Diagnostic page in Windows and let me know if Color is printing

1. Load plain paper into the input tray.

2. Search Windows for your printer model name, and then click the printer name in the list of results.

   HP Printer Assistant opens.

3. Click Maintain Your Printer.

4. On the Device Services tab, click Print Quality Diagnostics Page .

   A Print Quality Diagnostic page prints.

   Figure : Print Quality Diagnostic page without defects

   

Keep me posted

Thanks for replying!

If the photocopies do not show black ink on it, try the steps from the document Fixing Poor Print Quality to resolve the issue.

And yes, when you receive the black ink check and keep me posted.

This is my third day and approximately 30 hours of going through over 50 searches on HP to fix my problem.  Your technical number hangs up on you.  To buy a product from HP, even if a cheap one, I expected better help to correct this not connect to network, not connect to computer, etc.  It goes on and on and its a catch 22.  I absolutely give up.  If isn't the drivers then what the heck is it.  You telling to to go to 123...... it a real laugh.  I am so disappointed in my last two HP selections.  I even invested a new desktop and it doesn't work right either.  I feel as though I have lost $600.00 with my last HP purchases.
