Cannot add printer in windows

[turbospielt]

I installed everything on a Raspberry Pi4 in Docker. I had to change the port from 631 to 630 because the port is already in use. The printer can be accessed in the web Ui without any problems and the test page print too. Unfortunately I can't find or add the printer in Windows?
