Welcome to the HP support community.
Did you make a copy and check if that prints fine?]
Meanwhile:-
Run a Print Quality Diagnostic report
Use a Print Quality Diagnostic report to check if the printhead or ink cartridges need to be cleaned or if there is an alignment issue.
-
Load plain white paper in the tray.
-
Print the report.
If that does not prints fine, follow the below steps to fix the issue:-
-
Load plain white paper in the tray.
-
Run the cleaning tool.
: 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 cleaning tool.
-
If the page that prints has defects, the printhead might be badly clogged. Run up to two more cleaning cycles.

Cheers.
