Welcome to the HP Support Community. I'd be happy to assist you with the print quality issue.
To better assist you -
1) Are you using genuine HP inks?
2) Are you experiencing this issue while making a copy as well?
3) What's the application that you are trying to print from?
4) May I have the exact model name of the product? Refer to this document for steps to find the product details. Do not share any of your personal information such as serial, phone number, email ID, etc. Is this an HP OfficeJet Pro 6830 printer?
While you respond to that, try these steps - HP OfficeJet Printers - Fixing Print Quality Problems
Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware
Hope this helps! Keep me posted.
