Interesting article, but this is a mute point since most of the devices are behind FWs

With PoC code now available, an attacker could easily scan for and collect a list of vulnerable devices that are publicly accessible.

From my understanding, most of the printers are behind firewalls; however, if there is lateral/horizontal movement, the end-user or admin has bigger problems that need to be addressed (per the statement made by the speaker). In certain instances, I can see where certain cameras might be affected because they are connected directly to the internet (traffic cameras) and some of their IP Addresses are made public, but I am not sure how many IOT devices are connected directly to the internet. There is a site on the web that indicates a number of devices connected directly to the internet but that is part of another conversation - https://www.shodan.io/explore

I do see limitations in the statements made but it is possible, we just need to remain vigilant. A possible remidy would be to connect using SHA Hash 256 to the OS because the system could determine if the hash was found on the network or a token process where a PIN is used (a number of printers have this capability but most people don't use it).
