How to clear the list of known printers

I recently upgraded to macOS Tahoe and now when I attempt to print the print center shows me a long list of known printers instead of the 5-6 printers actually installed on my device.

I manage over 70 network printers for a school district and I have installed and tested each of these printers in the past. We also have 30+ non-shared printers that are used in individual offices. All printers are configured to use AirPrint, so I also see all of these printers as well. Many of which are only identified by their mDNS or Bonjour name. So far this is only an issue for me, but I am very hesitant to allow my users to upgrade to Tahoe until I can confirm this is not a Tahoe bug.

Any suggestions will be greatly appreciated.

Would you go to the Printers & Scanners in System Settings

and then click on the Printer you want to remove and remove the Printer. If you are on a School setup it might be more difficult since I believe that it would fall under Device Management.
