Android Question Barcode Printer - Problems

[Paul Garcia]

good afternoon,
I had problems printing with the Bluetooh TSC Alpha 3RB printer from an android application,
I have tried many codes exposed in the Forum but without success.
the codes do not generate errors, it even connects to the printer by bluetooh since the Led turns on but does not print anything.

attached code and image of the printer,
please your help for this problem.

are you printing a barcode?

Did you try this "hello world"? (it worked for me)
