Hi,
if you’re reading this message, it’s highly likely that your printer is exposed to the public internet via port forwarding. This means that *anyone* on the internet with some technical knowledge can send print jobs to your printer – or worse, try to exploit it and use it as a part of a global botnet.
If you didn’t intend for this, please look into disabling UPnP (Universal Plug and Play) on your router, or remove the port forwarding rule for the port 9100.
