There's no doubt the NBN network has some great benefits for business productivity.
But if you're planning to switch to it in the future, you need to be mindful of a few implications it can have on your print hardware if yours is managed by an external provider. (Unfortunately, NBNCo don't outline these implications anywhere on their website as at the date of writing this article. )
Just like your computers, your managed print devices also have an IP address.
When the NBN gets installed, your computers can detect the change on their own and automatically get reassigned with a new IP address.
Your managed print devices are not set up to reassign a new address in the same way. It needs to be done manually along with the Gateway, DNS & SMTP settings.
