@PennyRR, Welcome to HP Support Community!
I would recommend you follow the steps from the document HP OfficeJet 6900 Printers - Black or Color Ink Not Printing, Other Print Quality Issues.
Update the printer firmware
Download available firmware updates from the HP website
With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates.
For more information, go to Updating or Upgrading Printer Firmware.
Hope this helps! Keep me posted.
