It's about the same as the file generated on the USB from the printer through the WiFi menu, it just autofills the SSID and passkey to what's set in its menu. The other sections of the .ini which seem to set static IPs and more advanced options seem to be entirely missing, so my attempts to do that have been to copy chunks of code off of github and try to configure it to a way that makes sense to me - not sure there's an official configurator for it.
