@rohitatcoffee please try to using this function : printImageBase64
Yes, I tried that one too. printImageBase64 only takes base64 data not local image URI.
I am using Everycom EC-58 58mm printer
from react-native-thermal-receipt-printer-image-qr.
you can using this lib to capture -> covert to base64-> print
https://github.com/gre/react-native-view-shot
from react-native-thermal-receipt-printer-image-qr.
I am doing the following things,
- Render data in Webview
- Capture screenshots using https://github.com/gre/react-native-view-shot
- 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 :

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

what is the best dimensions?

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