XP-245 - How to Block auto firmware update

Recommended Posts

I've been using XP-245 chipless frimware for years, however I found that my printer will automaticly update to 20.25.EF20J9 which is not supproted by chipless frimware 3-4 times a year.
I'm sure that it is not conducted by computers as I'm using the printer wirelessly without USB connection.

Each time I have to follow previous guide to downgrade the firmware.
Is it possible to block this kind of auto firmware upgrade or having a chipless firmware with EF20J9?

Good day, are you sure that you do not have epson software updater installed and autoupdate is disabled in the driver settings? As far as I know this printer does not support autoupdate by itself, but if you have corresponding epson software it can update the printer even via Wi-Fi connection.
