Epson Printer Driver installation fails.
I am using a 2014 Mac Mini running Monterey 12.7.6 and it cannot be upgraded to Ventura due to its age.
I have down loaded the dmg file which Epson Support tells me is the correct one for my new Epson SC P706 (known as the P700 elsewhere). This printer driver installation fails. Epson suggest it is a security issue but in Privacy and Security the Firewall is turned off.
Epson suggested I create a new Admin User but the driver installation failed here as well.
I have reset the Printer Software in Printers and Scanners in System Preferences with no better success.
Any suggestions gratefully received.
Mac mini, macOS 12.7
