A cordova plugin for bluetooth printer for android platform.
This code is being adapted from a fork of Cordova-Plugin-Bluetooth-Printer, of free use and modifications that will arise for the improvement of the plugin.
Suggestions, critiques are welcome, participate and send a commit helping to improve the plugin for the community.
Thanks!

- Print image from path with align
- Print image from base64 with align
- Print title with size and align
- POS printing
- Print QRCode
- Print Barcode
Using the Cordova CLI and NPM, run:
cordova plugin add https://github.com/CesarBalzer/Cordova-Plugin-BTPrinter.git
Get list of paired bluetooth devices, including printers, if any:
BTPrinter.list(function(data){
console.log("Success");
console.log(data); // paired bluetooth devices array
},function(err){
console.log("Error");
console.log(err);
});
Returns an array with the format:
data[0] = Device 1 name
data[1] = Device 1 MAC address
data[2] = Device 1 type
data[3] = Device 2 name
data[4] = Device 2 MAC address
data[5] = Device 2 type
...
Where device name is the required string to connect to the printer.
BTPrinter.status(function(data){
console.log("Success");
console.log(data) // bt status: true or false
},function(err){
console.log("Error");
console.log(err)
});
BTPrinter.connect(function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
}, "PrinterName");
BTPrinter.connected(function(data){
console.log("Success");
console.log(data) // connected: true or false
},function(err){
console.log("Error");
console.log(err);
});
BTPrinter.disconnect(function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
}, "PrinterName");
I thought it best to create the function within a timeout
setTimeout(function(){
BTPrinter.disconnect(function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
}, "PrinterName")
}, 1500);
BTPrinter.setEncoding(function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
}, "ISO-8859-1")
Refer to printer's manual for supported encodings and codepages.
BTPrinter.printText(function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
}, "String to Print")
BTPrinter.printTextSizeAlign(function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
}, "String to Print",'0','0')//string, size, align
BTPrinter.printImageUrl(function(data){
console.log("Success");
console.log(data);
},function(err){
console.log("Error");
console.log(err);
}, "Path String",'0');//path image, align
In android tests with /storage/emulated/0/Pictures/myfolder/myimage.jpg - size max: 300x300px.
- with align still in tests not work alignment)
BTPrinter.printBase64(function(data){
console.log("Success");
console.log(data);
},function(err){
console.log("Error");
console.log(err);
}, "Image Base64 String",'0');//base64 string, align
- with align still in tests not work alignment)
BTPrinter.printTitle(function(data){
console.log("Success");
console.log(data);
},function(err){
console.log("Error");
console.log(err);
}, "String text",'0');//string, size, align
BTPrinter.printPOSCommand(function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
}, "0C");//OC is a POS command for page feed

To test most of the plugin's functions, you can use the free BTPrinter Plugin Demo app by Andrés Zsögön, and inspect the source code for more details.
The following sample receipt was printed with the plugin demo app using a generic portable bluetooth printer:
