Has anyone worked with a thermal printer mobile app?
When I try to print Cyrillic letters, they turn into Chinese symbols. Even when I convert the data into an image and print it, it still shows as Chinese symbols.
I’m using the RPP300 80mm Rongta.
However, when I use their RTPrinter app to print an image, it works fine.
And, I am using React Native and implementing native Kotlin code.
