Is it possible to open the cashier drawer within this lib?

[ZheruiL]

Hi, I've just tried your lib and it worked perfectly for my device.

I would like to know is it possible to open the cashier drawer within this lib? Because I've read the official document there's a function called void openDrawer(ICallback callback) but I don't know how to apply it. could you help please?

Thanks before
