String str = "";
1. Print text data
Add Content; where
B: bold status and value must be 0 if no and 1 if yes
A: align status and value must be 0 if left, 1 if center, 2 if right
F: format type and valune must be 0 if normal, 1 if double Height, 2 if double Height + Width, 3 if double Width
Content: Content is text that you want to print with given format
e.g. str = str + "<110>This is my testing data";
2. Print image
Add A#Base64; where
A: align status and value must be 0 if left, 1 if center, 2 if right
Base64: Base 64 encoded string derived from below function
//Send parameters like pageWidth and filepath where
//pageWidth is page width e.g. 48 for 58mm printer, 72 for 80mm printer
//filePath is complete image file path
private String getBase64(int pageWidth, String filePath) {
//You can modify below program as per your requirements provided that you return base64 string corresponding to the image
//Also check if filepath is not null and your app has required permissions before calling this method

}
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, compressValue, byteArrayOutputStream); // bm is the bitmap object
return Base64.encodeToString(byteArrayOutputStream.toByteArray(), Base64.DEFAULT);
}
3. Print Barcode
Add A#W#H#Value; where
A: align status and value must be 0 if left, 1 if center, 2 if right
W: Valid barcode width
H: Valid barcode height
Value: Valid barcode value
e.g. str = str + "0#100#50#2132137538472";
4. Print QR Code
Add A#S#Value; where
A: align status and value must be 0 if left, 1 if center, 2 if right
S: QR Code Size
Value: Valid QR Code value
e.g. str = str + "1#50#This is sample";
5. Print HTML
Add Code where
Code: This is an HTML code to be printed; Put escape character before "
e.g. str = str + "" + getHTMLEquivalent("
This is left
This is right
");
Add below function for HTML
private String getHTMLEquivalent(String s) {
return s.replaceAll("<","<").replaceAll(">",">");
}
To say in simple words, You can create an example string like below
String imgpath = Environment.getExternalStorageDirectory().toString()+"/BluetoothPrint/test.jpg";
String str = "<113>Mate Technologies<100>Website: www.matetech.in\nEmail: matetusshar@gmail.com1#"+imgpath;
str = str + "0#100#50#21321375384721#40#testing text";
str = str + "
This is left
This is right
";
Just pass this to Bluetooth Print app using Intent below
//check if app is already installed to avoid crash
if(appInstalled){
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("mate.bluetoothprint");
sendIntent.putExtra(Intent.EXTRA_TEXT, str);
sendIntent.setType("text/plain");
startActivity(sendIntent);
