Greetings,
If you printer is behind a firewall, the vulnerabilities cannot be exploited. It would have to be connected to a directly to the internet.
"If the product is connected directly to the internet without using a wired or Wi-Fi router, a third party could potentially execute arbitrary code or the product could be subjected to a Denial-of-Service (DoS) attack."
I searched and did not see any firmware downloads for your device either. You'll have to reach out to support directly for further assistance.
