Friends I am half new in programming android studio, I have a thermal printer Zebra IMZ320, I read in some places to download the sdk. but I do not understand or anything, there is a test apk of them called Zebra utilites, which does what I want but they do not give the source, I am super lost, and once I programmed for another Chinese printer but that if I brought an example program and it was only question of integrating that to my app. but with this printer I do not understand anything. Help please
