Anyone know which ip addresses to block to stop the updates?
If you set the wrong gateway in the static IP settings or a reserved DHCP lease, it won't be able to get out.
But will it be able to be reachable by other printers on the network?
It will be reachable by LAN. The gateway address is the router you use to get to addresses outside the subnet mask you set.
First search result explains it more thoroughly if you're interested

Good to know, and thanks for the link!
Why? Does the printer need to be connected to the internet at all, if not for firmware upgrades? (Note: LAN != internet)
Many people use WiFi to connect to their printers for the sake of convenience
You can have devices on your wifi network without giving them access to the internet. You set your firewall (which, for most people, is the router that comes with the internet subscription) to block all internet traffic to and from those devices while still allowing them to communicate with the other devices on the same local network. Fairly straightforward on most routers with a little bit of time spent looking up the basics.
Exactly what I meant with
Most routers allow you to set child safety settings for devices to block them from accessing the internet in specific timeframes or completely. You can still access the local network from the affected device or access that device from your local network
