Welcome to the HP support community.
Did you make a copy and check if that prints fine?
Meanwhile:-
Run the automated printhead or ink cartridge cleaning tool
Clean the printhead and cartridges to resolve print quality issues including incorrect colors, streaks, and faded prints.
-
Load plain white paper in the tray.
-
Run the cleaning tool.
-
Printers with a touchscreen or menus: On the printer, open the Settings or Setup menu, touch Tools or Printer Maintenance, and then touch Clean Printhead or Clean Cartridges.

Cheers.
