Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Did you make any changes to your printer? 
• Does the copy print out the same way?

While you respond to that, let's try these steps: 

To begin with, prepare your printer for a wireless connection, restart the printer, computer, and router. 

1. Turn the printer off, and then wait 10 seconds. 

2. Disconnect the printer power cord from the printer. 

3. Turn off the computer or the device you are trying to print from. 

4. Connect the printer power cord to the printer, and then turn on the printer. 

5. Disconnect the power cord from your wireless router, and then wait 10 seconds. 

6. Reconnect the power cord to the router. Wait until Internet service is restored. Internet service is interrupted while the router is off. 

7. Turn on the computer. 

And, also refer to the article: No black ink, wrong colors, other print quality issues By the end of the article you will be able to isolate the issue.

Hope this helps! Keep me posted for further assistance.
