Printing Unicode Characters From android to bluetooth thermal printer

问题

I have bluetooth/usb thermal Printer of model QS58. I want to print unicode characters like "मराठी"

When i connect printer to computer through usb and give print,it prints correctly. but, when printing through my android application it is printing invalid characters(chinese character).

I think windows is sending correct data to printer,but my application not.so please tell me ho can i send data to printer.

I have already tried following methods

mmOutStream.write("मराठी".getBytes("UFT-8"));

mmOutStream.write("मराठी".getBytes("UFT8"));

mmOutStream.write("\u0991\u0992".getBytes("UFT-8"));

mmOutStream.write("\u0991\u0992".getBytes());

回答1:

You've got your encoding as "UFT-8". Should this not be "UTF-8"??

回答2:

You shouldn't be able to do that. In documentation states that it only prints:

Printable content: English, numbers, symbols, Chinese characters

also Instruction set: ESC/POSCompatible instruction set

So maybe your charactares (i don't know what language is that) are in some region page code of ESC/POS.
