React-native-datecs-printer NPM

react-native-datecs-printer

It only works on Android and have only few specific methods.

As I made this project with a very short deadline, it's specific for the app that I was working on. My plan is to make a full port of cordova-plugin-datecs-printer for React Native.

if on RN < 0.47.2 npm i react-native-datecs-printer@0.1.1
