Ipad printing from iPrint&Scan app

Have always been able to print from my iPad through the app iPrint& Scan until I downloaded Catalina on my new Apple Mini Mac.

However, on the iPad print app this time it says "Please confirm the following - "Check that the Wi-Fi access point/router's "privacy Separator" option is "displayed". What does that mean? And where do I check this question that is appearing on my iPad out?
