Greertings,
Can you please tell us more about your environment. How is the printer connected? To a network, to your your computer via USB, etc?
New drivers specifically for catalina were released last month on the 26th. Please confirm you are using them before you start troubleshooting. If neccessary, remove the printer and uninstall all old drivers, then reinstall using (10.15) compatible drivers
