Welcome to the HP support community.

Did you make a copy and check if that prints fine?

Meanwhile:-

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.

If that does not print fine, follow the steps mentioned in this HP document to fix the issue:- Click here

I hope that helps.

After trying everything from running diagnostics on the PC, to cleaning the printhead, resetting the alignment, manually cleaning the printhead, nearly taking apart my whole printer,  I finally got it working - without having to buy a new printer or replace the ink cartridges.

Run the "Clean Printhead" like ten times. At first, I was getting a blank page with three colored bars on it. This kept occuring probably at least 5 times. But, I continued running "Clean Printhead" until it printed the whole diagnostic page and started working. 

If that doesn't work, I saw on one acclaimed reply that putting a thin piece of clear tape on the ink cartridge connectors got it working for numerous others! I wanted to avoid manipulating the printer itself so the first solution got mine working again.
