I would love to see this as well.

Being able to use React-native is awsome. And being able to adjust fonts would be great.

First install yarn add base64-js After ` import base64 from 'base64-js';

    var boldActive = [0x1b, 0x45, 0x1];
    var boldCancel = [0x1b, 0x45, 0x0];
    var boldActiveStr = base64.fromByteArray(boldActive);
    var boldCancelStr = base64.fromByteArray(boldCancel);

    await SunmiInnerPrinter.setFontSize(30);
    await SunmiInnerPrinter.sendRAWData(boldActiveStr);
    await SunmiInnerPrinter.printOriginalText(' Text ');
    await SunmiInnerPrinter.sendRAWData(boldCancelStr);

Thank you! This is great. You made my day! You don't happen to know a way to change fonts as well @mitchelson ?
