I think you have implemented BluetoothTscPrinter package yet. all other commands are working as they are called with BluetoothEscposPrinter, for Example, this BluetoothEscposPrinter.printText("Hello world\n\r",{}); works completely fine. — You are receiving this because you are subscribed to this thread.

Ohh sorry... I am using expo sdk 31, which is based on React Native 0.57. You have done amazing job by creating this package. It would be better if it can be easy to integrate. I don't know why I am facing so many problems.

see, here is the screenshoot of warning I am receiving with printLabel.
and I am passing options as

initPrint = async () => {
    const options = {
        width: 40,
        height: 30,
        gap: 20,
        direction: BluetoothTscPrinter.DIRECTION.FORWARD,
        reference: [0, 0],
        tear: BluetoothTscPrinter.TEAR.ON,
        sound: 0,
        text: [{
            text: 'I am a testing txt',
            x: 20,
            y: 0,
            fonttype: BluetoothTscPrinter.FONTTYPE.SIMPLIFIED_CHINESE,
            rotation: BluetoothTscPrinter.ROTATION.ROTATION_0,
            xscal:BluetoothTscPrinter.FONTMUL.MUL_1,
            yscal: BluetoothTscPrinter.FONTMUL.MUL_1
        },{
            text: '你在说什么呢?',
            x: 20,
            y: 50,
            fonttype: BluetoothTscPrinter.FONTTYPE.SIMPLIFIED_CHINESE,
            rotation: BluetoothTscPrinter.ROTATION.ROTATION_0,
            xscal:BluetoothTscPrinter.FONTMUL.MUL_1,
            yscal: BluetoothTscPrinter.FONTMUL.MUL_1
        }],
        qrcode: [{x: 20, y: 96, level: BluetoothTscPrinter.EEC.LEVEL_L, width: 3, rotation: BluetoothTscPrinter.ROTATION.ROTATION_0, code: 'show me the money'}],
        barcode: [{x: 120, y:96, type: BluetoothTscPrinter.BARCODETYPE.CODE128, height: 40, readable: 1, rotation: BluetoothTscPrinter.ROTATION.ROTATION_0, code: '1234567890'}],
        // image: [{x: 160, y: 160, mode: BluetoothTscPrinter.BITMAP_MODE.OVERWRITE,width: 60,image: base64Image}]
     }

BluetoothTscPrinter.printLable(options)
    .then(()=>{
        //success
    },
    (err)=>{
        //error
    })

Sorry，never tested with expo.

[januslo]

you may need to do some alert/log in the index.js to figure out what is the problem. It's a good idea to start with the NativeModules after this line:

const {BluetoothManager,BluetoothEscposPrinter,BluetoothTscPrinter}= NativeModules;

Now package is integrated, other functions are running fine, but Bluetoothtcsprinter.printlabel not working. And I am not passing base 64 image. So image key is commented. But I want to use qr code and bar code

Here is a real case as a sample :

    await BluetoothTscPrinter.printLabel({
                        width: labelConfig.width,
                        height: labelConfig.height,
                        gap: labelConfig.gap,
                        direction: BluetoothTscPrinter.DIRECTION.FORWARD,
                        reference: [0, 0],
                        tear: BluetoothTscPrinter.TEAR.ON,
                        sound: 1,
                        text: texts,
                        barcode: barCode,
                        home:  0
                    });

No everything need for printing a label. further more , printLabel not printlabel

[shubhamdeol]

okay, so if I don't want image, and I want barcode only in that case it won't work ?

see, here I am getting this function, but properties like DIRECTION are not getting attached to object may be :(

hey tell me one more thing, if BluetoothEscposPrinter and BluetoothTscPrinter are different kind of printer. I have Escposprinter, so maybe it does not detect BluetoothTscPrinter
