Unable to print image of Subsystem in Simulink model in 2016b

The command:

print('-sBatteryEmulator','-dbitmap','ModelName')

is giving an error :Attempt to call a method on an empty value

This command works well in 2020 and 2019 but gives the error in 2016b

I am attaching the model image for reference ,here BatteryEmulator is the subsystem whose image I want to generate ,but I am unable to generate the image of what's inside subsystem in 2016b.

can you please tell me why it is not working in 2016b?

In R2016b, it seems that the Subsystem needs to be open first. Add a line open_system() first.
