    Printer heads need cleaning. There should be a utility for that in the printer's software (probably under maintenance). If that doesn't solve it, you'll need to bring the printer to the service center for an actual physical scrub down.

    If you can locate a store that sells compatible printer ink, ask for a bottle print head cleaner solution then go to Youtube to learn how to do it yourself.

    It seems that your printhead is blocked, my friend.

    The following webpage, on YouTube.com, shows you how to remove and clean printheads on HP Printers.
