I am working on a sales application and need to print to a USB connected fiscal epson printer
I want to use the manufacturer's library called "EpsonFiscalDriver.aar":
and I can't get the printer to answer me something. I can only read the version of the library "EpsonFiscalDriver.aar"
What am I doing wrong....
I have some examples of the use of the library delivered by epson

I am a newbie to b4a I started using it in June 2020

Apologies for my bad english

Thanks so much for any help
