Writing the configuration script to the printer
You can save a configuration script to the printer using the HTTP POST method.
You can save the configuration script to volatile or non-volatile memory.
When changing using a low frequency less than once an hour, you can save to non-volatile memory; however,
when changing at a higher frequency, you need to save to volatile memory.
When the change is successful, the advertising data is changed.
