I cannot print to my HP Officejet Pro 8600 after my Mac updated to Catalina 10.15.2.

I cannot print to my HP 8600 after my system just updated to Catalina 10.15.2.  I have turned my computer off and my printer off.  I have also tried to reinstall the print drivers.  Nothing is working.  I am not very tech savvy and have no clue what else to do.  When redownloading the printer drivers, it says that the certification is expired.  What can I do to fix this?  I use this printer for my business and it is keeping me from being productive.  Any help would be appreciated.

Hi,

Please download and install the latest drivers from Apple below:

Once completing the installation, reset the printing system as following:

*Be aware that resetting the printer system will remove any existing print queue and reset any customized driver settings.

Click the Apple menu, and then click System Preferences.
Select Printers & Scanners.
Right-click (or Ctrl + click) your product in the Printers list in the left panel, and then click Reset printing system.
Click OK to confirm the reset.
Type your user Name and Password.
Click OK. The printing system resets.

Now press the plus sign and select the listed printer, be sure to select the HP Officejet Pro 8600 option within the Use drop-down menu.
