@chukiatt I don't have a bluetooth printer at the moment so I can't develop and test this feature yet! but I'll try to find a way to guide you through its development and testing.!

[thiendangit]

@chukiatt if you only develop print feature for android and bluetooth you can try using this library: https://www.npmjs.com/package/react-native-thermal-printer

[chukiatt]

I already use your suggested library https://www.npmjs.com/package/react-native-thermal-printer . but it can not print qrcode and image. Until I found the library react-native-thermal-receipt-printer-image-qr. I see it can print qrcode and image in your doc.

[chukiatt]

very welcome

thank you very much

[thiendangit]

@chukiatt please try again!

[chukiatt]

after update to "react-native-thermal-receipt-printer-image-qr": "^0.1.3", i got this error

TypeError: RNBLEPrinter.printImageData is not a function

[thiendangit]

@chukiatt i added it in v0.1.3 for android version already! try to remove yarn.lock and react-native-thermal-receipt-printer-image-qr in your node_modules and try again!

[chukiatt]

@thiendangit i will try again and response to inform you

[chukiatt]

@thiendangit i make sure by created a new react native app for test and then install only your library

npx react-native init testProject npm install react-native-thermal-receipt-printer-image-qr
react-native run-android --deviceId=SWTOAIKNM78TCYSW

app build success. but printImage is still error

TypeError: RNBLEPrinter.printImageData is not a function. (In 'RNBLEPrinter.printImageData(imgUrl, function (error) { return console.warn(error); })', 'RNBLEPrinter.printImageData' is undefined)

[thiendangit]

@chukiatt Ahhh sr. i see this error! I’ll fix it in the morning.

[chukiatt]

Thank you very much

[thiendangit]

@chukiatt i fixed in v0.1.4

[chukiatt]

@thiendangit It's work. I am very glad

i not sure it's support both Android and iOS ?

Thank you very much

[thiendangit]

@chukiatt Does Android work? if you want to print pictures with bluetooth in ios or with base64 uri, I can help you!

[chukiatt]

@thiendangit Yes, i want to print in both platform include base64 uri

my goal is draw everything to image (text and picture) and export to base64 toDataURL() to print. this idea is pretty good for almost printer can print without a problem (not only epson and star)

thanks for your help

[thiendangit]

@chukiatt ok i'll try it tonight 😁

[thiendangit]

@chukiatt please try :

• [ ] Add this line to package.json :

react-native-thermal-receipt-printer-image-qr : "https://github.com/thiendangit/react-native-thermal-receipt-printer-image-qr.git"

• [ ] Using function printQrCode to print image with base64 in android and ios!
• [ ] Using function printImage to print image with url in android and ios!

[chukiatt]

@thiendangit

Thank you for your help. Your library will be an important part of the build POS project. of Thailand

Thank you very much

[thiendangit]

@chukiatt is print BLUETOOTH working? if it working, i'll release new version!

[chukiatt]

Yes, now i tested only bluetooth, It's work well.

[thiendangit]

@chukiatt wow! many tks :tada:. Both android and ios are ok? ? give me star if you like my repos :kissing_closed_eyes: :kissing_closed_eyes:

[thecodecafe]

Hi @thiendangit, this is a great library, I just tried BLEPrinter.printQrCode(base64EncodedImage) and got an error saying printQrCode is not a function in RNBLEPrinter.printQrCode(qrCodeBas64, function(error) {return console.warn(error);}) RNBLEPrinter.printQrCode is undefined. I've given a star! 😊

[Edit] This is happening on Android, this is the only platform I can test for right now. The problem was that in RNBLEPrinter the printQrCode method does not have @ReactMethod so it's not exported in NativeModules.

[thiendangit]

@thecodecafe many tks! I was careless
