Hi @Malc-71_hil,

 I'd like to help!

I understand you are facing print quality issues.

To assist better-

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

Use HP Printer Assistant to print a Print Quality Diagnostic page in Windows.

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 .

Use HP Utility to print a Print Quality Diagnostic page from your Mac.

1. Load plain paper into the input tray.

2. Click the Apple menu, and then click System Preferences.

3. Depending on your version of OS X, click Print & Scan or Printers & Scanners.

4. In the Print & Scan or Printers & Scanners window, select your printer, and then click Options & Supplies.

5. Click Utility, and then click Open Printer Utility.

   HP Utility opens.

6. Click Print Quality Diagnostics , and then click Print.

   A Print Quality Diagnostic page prints.

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