+# Broadcast for Bambu P1P Printer
+
+The python script included was made so I could use Bambu Studio without the need for an internet connection. Additionally, I wanted the printer to be isolated on an IoT vlan with a statically assigned ip address, allowing only necessary traffic.
+
+For discovery, the printer uses SSDP protocol, and this python script will replicate what the printer sends.
+
+You will need to replace the following values in the script:
+
+- `10.10.10.10` with the ip address of the printer
+- `000000000000000` with the serial number of the printer
+
+Once updated, run the script and it will broadcast the packet on the local interface
