Print local image

[rohitatcoffee]

Is there any way to print local images? I tried converting the image to base64 but the printer is printing garbage data. But I passed image link then it get printed.

Yes, I tried that one too. printImageBase64 only takes base64 data not local image URI.
I am using Everycom EC-58 58mm printer

you can using this lib to capture -> covert to base64-> print
https://github.com/gre/react-native-view-shot

I am doing the following things,

1. Render data in Webview
2. Capture screenshots using https://github.com/gre/react-native-view-shot
3. Then convert screenshot to base64 using react-native-fs and print using Printer.printImageBase64(res, { beep: false, imageWidth:600});

But still getting messed up data.

maybe your base64 is wrong!
try this :

react-native-thermal-receipt-printer-image-qr/example/src/HomeScreen.tsx

Line 191 in 54b4ec9

let qrProcessed = dataURL.replace(/(\r\n|\n|\r)/gm, "");

@thiendangit I am able to solve this issue, the issue was the width. I was passing images with the wrong dimensions.

if you are printing in a small printer use image width less than 200 or 300 @rohitatcoffee
