how to print base64 image? I tried to print base64 image but it did not work.
const printing = new EscPosPrinter.printing(); const status = await printing .initialize() .imageBase64(img, 540) .cut() .send();

For now, printing from the base64 source is not stable. We need to investigate what is the problem with this method.

So I'd recommend print image from assets folder instead.

I need to print remote image. Is there any solution to print remote image uri ?

[tr3v3r]

@venky2604 I think I need some time to investigate why current implementation about base64 doesn’t work, so then I think it will possible print from remote source.

When I changed Base64.URL_SAFE to Base64.DEFAULT in

react-native-esc-pos-printer/android/src/main/java/com/reactnativeescposprinter/EscPosPrinterModule.java

Line 508 in ba2ed89

byte[] decodeBase64ImageString = Base64.decode(base64ImageString, Base64.URL_SAFE);

it is working.
