printViaSDK gives error about cordova-brother-label-printer

[firdaus48]

@VictorCoding this issue has been solved, with update the latest SDK that supported QL-1110NWB model.

Thank u

[VictorCoding]

are you including data:image/png;base64, if so you shouldn't. just include everything else after that.

[gordol]

Correct, you should only send the image data. It does not specify to use a data URL, but base64 encoded image.

printViaSDK takes one parameter, which is a base64 encoded bitmap image. The result should be a status code that is passed directly from the SDK. The status codes are documnted in the Brother SDK Appendix in section 4.2.2.5.Error Code. If everything works, the response should be "ERROR_NONE".

Hello,
Thanks for your response.
I tried that too. But when i pass base64 string without data:image/png;base64, the app is crashed.
So can you provide me a sample code for it.

When I try to debug in BrotherPrinter.java file, I note one thing I got base64 image but my application is crashed when "mBitmapPrint.print();" is called.

Thanks in advance.

@chetuBhadra93 can you share your code?

What platform are you on?

Have you tried the master branch?

I cannot vouch for the validity of the dev branch, as it is un-tested.

[chetuBhadra93]

Hello,
Thanks for response.
I am using android platform and dev branch.

[gordol]

Does the master branch work for you? @chetuBhadra93

[chetuBhadra93]

Yes, I tried master branch. I got printer in findPrinter but when i call printViaSDK it does not give any error but it also not printing anything. And when i try to debug I log this info.
"Model: QL_720NW Port: NET PrintMode: ORIGINAL Orientation: PORTRAIT PaperSize: CUSTOM ipAddress: 192.168.x.xx macAddress: 54:xx:xx:xx:xx:xx"

My model number is: QL-810.

what should i pass for my model in this code
"myPrinterInfo.printerModel = PrinterInfo.Model."

Can you please help me to figure out this issue..?

[chetuBhadra93]

I successfully print label for Model QL-810 using Master branch for android platform.

Hi, i am getting error while calling printViaSDK. The error is 'The passed in data did not seem to be a decodable image. Please ensure it is a base64 encoded string of a supported Android format'.
I have excluded data:image/png;base64 as mentioned by @VictorCoding. can someone help me on this please, thanks in advance.

cordova.plugins.brotherPrinter.findNetworkPrinters((data)=>{
        var printerResponse = data[0];
        var printer = {
          "model": printerResponse.model,
          "port": printerResponse.port,
          "modelName": printerResponse.modelName,
          "ipAddress": printerResponse.ipAddress,
          "macAddress": printerResponse.macAddress,
          "nodeName": printerResponse.nodeName,
          "location": ""
        }

        cordova.plugins.brotherPrinter.setPrinter(printer, function (success) {
          var imageString = base64Image.split(',')[1];
          var dataArray = {
            "base64String": imageString,
            "numberOfCopies": 1
          };
          cordova.plugins.brotherPrinter.printViaSDK([dataArray], (data) => {
            console.log('print success');
          }, (error)=> {
            console.log('error:', error);
          })
        });
      },(err)=>{
          console.log("Error");
          console.log(err)
});`

Maybe the base64 is corrupted? I would validate that it's actually valid just for a sanity check. Stick it in an image tag to verify.

@VictorCoding it is a valid image i am display while printing the badge <img src="{{base64Image}}" width="200" height="200">

[VictorCoding]

@yogeshshsf welp, no idea then 🤷‍♂

[gordol]

Try a bitmap instead of png?
