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!
Using the Cordova CLI and NPM, run:
cordova plugin add cordova-plugin-bluetoothprinterGet list of paired bluetooth devices, including printers, if any:
BluetoothPrinter.list(function (data) {
console.log("Success");
console.log(data);
},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 typeWhere device name is the required string to connect to the printer.
BluetoothPrinter.status(function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
})BluetoothPrinter.connect("PrinterName", function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
})BluetoothPrinter.isConnected(function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err);
})BluetoothPrinter.disconnect("PrinterName", function(data){
console.log("Success");
console.log(data)
}, function(err){
console.log("Error");
console.log(err)
})I thought it best to create the function within a timeout
setTimeout(function(){
BluetoothPrinter.disconnect("PrinterName", function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
});
}, 1500)BluetoothPrinter.setEncoding("ISO-8859-1", function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
})Refer to printer's manual for supported encodings and codepages.
BluetoothPrinter.printText("String to Print", function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
})BluetoothPrinter.printTextSizeAlign("String to Print", 0, 0, function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
})BluetoothPrinter.printImageUrl("Path String", 0, function(data){
console.log("Success");
console.log(data);
},function(err){
console.log("Error");
console.log(err);
})In android tests with /storage/emulated/0/Pictures/myfolder/myimage.jpg - size max: 300x300px.
- with align still in tests not work alignment)
BluetoothPrinter.printBase64("Image Base64 String", '0', function(data){
console.log("Success");
console.log(data);
},function(err){
console.log("Error");
console.log(err);
})- with align still in tests not work alignment)
BluetoothPrinter.printTitle("String text", 0, 0, function(data){
console.log("Success");
console.log(data);
},function(err){
console.log("Error");
console.log(err);
})BluetoothPrinter.printPOSCommand("0C", function(data){
console.log("Success");
console.log(data)
},function(err){
console.log("Error");
console.log(err)
})var data = "https://github.com/CesarBalzer/Cordova-Plugin-BluetoothPrinter";

})Notice that UPC-A, UPC-E, EAN13 and ITF accepts only:
Numbers 0-9Sending other characters will return a plugin error with the proper description.
CODE39 accepts:
0 – 9, A – Z, SP, $, %, *, +, -, ., /CODABAR accepts:
0 – 9, A – D, a – d, $, +, −, ., /, :0 = CHAR_SIZE_01 // equivalent 0x1B, 0x21, 0x00
