Hi @BSHURST

Welcome to the HP Support Community. 

I understand that you are not able to print in color. 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 device? 

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

Load plain white paper into the tray.

Print the report.

Printers without a touchscreen or menus: Go to 123.hp.com or your app store to install the HP Smart app. Click the picture of your printer on the home screen to open printer management options that include the 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 the " Print Quality Issues" issue applicable to your printer - click here

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

 
You may also try the steps below:

Add the AirPrint printer to the Mac printer queue

Add the Air Print printer to the Mac printer queue

Confirm you are using Air Print by adding the printer in System Preferences.

1. Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.
2. Check if your printer name displays in the Printers list, and then do one of the following steps.
   • If your printer is listed, remove and re-add the printer to confirm it is set up for Air Print. Click the printer name, click the minus sign "-" to delete the printer, click the plus sign "+"click Add Printer or Scanner, click the printer name and then continue to the next step.
   • If your printer is not listed, click the plus sign, click Add Printer or Scanner, click the name of your printer, and then continue to the next step.
3. Confirm Air Print or Secure Air Print displays in the Use or Print Using menu, and then click Add.
