/**
|
|
* Utility to make a Bambu printer appear on the local subnet
|
|
* so that the Bambu Network Plugin can find it. The intended
|
|
* use case is where a printer is on another subnet but reachable
|
|
* directly (routable) and Bambu Studio / Orca Slicer can't find
|
|
* it because SSDP broadcasts do not cross subnets.
|
|
*
|
|
* When this process is run from the command line, it should appear
|
|
* under the slicer Devices tab when "+" is selected.
