POS bluetooth printer leaving some margin at start and then starts printing in Android App

I am implementing POS bluetooth printer with ESC/POS commands and trying to print bitmap image.
Image is getting printing but always it is printing some white space at start and then printing an image,because of which i am not able to print 1 image per label.
following is my code for printing and image
int bmpNewWidth = bmp.getWidth();
int bmpNewHeight = bmp.getHeight();
byte[] printBMPPackageHead = ESCUtil.bmpCmdHead(bmpMode,bmpNewWidth);
int bmpBlockHeight = 0;
int bmpBlockNums =0;
if((bmpMode == 0) || (bmpMode ==1))
{
bmpBlockHeight = 8;
}
else if((bmpMode == 32) || (bmpMode ==33))
{
bmpBlockHeight = 24;
}
else
{
Log.d(TAG,"****bmpMode set error!!*****");
return (new byte[1]);
}
bmpBlockNums = ((bmpNewHeight % bmpBlockHeight) == 0)? (bmpNewHeight/bmpBlockHeight) : (bmpNewHeight/bmpBlockHeight +1);
int bmpBlockCMDSize = printBMPPackageHead.length + bmpNewWidth*bmpBlockHeight/8;
byte[] bmpPrintData = new byte[bmpBlockNums*bmpBlockCMDSize];
for(int n = 0; n < bmpBlockNums; n++)
{
byte[] bmpBlockPxBytes = getBitmapBlockData(n,bmpNewWidth,bmpBlockHeight,bmp);
byte[][] bmpBlockPrintData = {printBMPPackageHead,bmpBlockPxBytes};
System.arraycopy(ESCUtil.byteMerger(bmpBlockPrintData),0,bmpPrintData,n*bmpBlockCMDSize,bmpBlockCMDSize);
}
return bmpPrintData;
}
and
public static byte[] bmpCmdHead(int mode, int bitmapWidth)
{
//byte[] result = new byte[]{ESC,42,0,0,0};
byte[] result = new byte[]{ESC,42,0,0,0};
result[2] = (byte)mode;
result[3] = (byte)(bitmapWidth%256);
result[4] = (byte)(bitmapWidth/256);
return result;
}
public static byte[] getBitmapBlockData(int blocknum, int bmpWidth, int bmpBlockHeight, Bitmap bmp)
{
int blockHeightBytes = bmpBlockHeight/8;
byte[] blockData = new byte[bmpWidth*blockHeightBytes];
for (int i = 0;i < bmpWidth; i++)
{
for(int j = 0;j < blockHeightBytes;j++)
{
for(int p = 0; p < 8; p++)
{
byte px = px2Byte(i,blocknum * bmpBlockHeight+j*8+p,bmp);
blockData[i*blockHeightBytes+j] |= (px << (7-p));
}
}
}
return blockData;
}
this is it.Before calling this function i have called only init printer command that's it.
Please help me. Thanks in advance.

tflite.run() returning same output for different input values

I am trying to make an android app for monument recognition. The input changes on every run but output returned is always same.
Below are the code snippets
to load tflite model stored in assets directory
private ByteBuffer loadModelFile(String filename) throws IOException {
AssetFileDescriptor fileDescriptor = this.getAssets().openFd(filename);
FileInputStream inputStream = new FileInputStream(fileDescriptor.getFileDescriptor());
FileChannel fileChannel = inputStream.getChannel();
long startOffset = fileDescriptor.getStartOffset();
long declaredLength = fileDescriptor.getDeclaredLength();
return fileChannel.map(FileChannel.MapMode.READ_ONLY, startOffset, declaredLength);
}
to initialize tflite interpreter
predict.setOnClickListener(new View.OnClickListener() {
#RequiresApi(api = Build.VERSION_CODES.O)
#Override
public void onClick(View v) {
try {
tflite = new Interpreter(loadModelFile("converted_model.tflite"));
Log.println(7,"tflite", "tflite init");
doInference(picFile);
} catch (Exception e) {
System.out.println(e);
}
}
});
to run the model
#RequiresApi(api = Build.VERSION_CODES.O)
public void doInference(File photo) throws IOException {
img = findViewById(R.id.imgToDisp);
Bitmap bitmapImg = BitmapFactory.decodeFile(pathToFile);
img.setImageBitmap(bitmapImg);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmapImg.compress(Bitmap.CompressFormat.JPEG, 50, stream);
byte[] arr = stream.toByteArray();
changedim = new float[1][150][150][3];
outputval = new float[1][28];
int m = 0;
for (int i = 0; i < 1; i++) {
for (int j = 0; j < 150; j++) {
for (int k = 0; k < 150; k++) {
for (int l = 0; l < 3; l++) {
byte a = arr[m++];
changedim[i][j][k][l] = Byte.toUnsignedLong(a);
}
}
}
}
tflite.run(changedim, outputval);
for(int i=0;i<28;i++) {
Log.println(7,"outputval",i+" "+outputval[0][i]);
}
path = findViewById(R.id.path);
String out = "";
float[] op = outputval[0];
int ind = 0;
float max = op[0];
while (op[ind] != 1) {
ind++;
//Log.println(7,"op", " "+op[ind]+" "+ind);
}
for (float f : op) {
out += Float.toString(f) + ",";
}
predict.setText("result: " + labels.get(ind));
Log.println(7, "label", ind + " " + labels.get(ind));
//path.setText(""+pathToFile);
}
input to the model must be an image of size 150*150 converted to 4d float32 array of shape 1*150*150*3

Input to the model is the color values of individual pixels.
Which can be extracted using
int p = bitmapImg.getPixel(j, k);
int R = (p >> 16) & 0xff;
int G = (p >> 8) & 0xff;
int B = p & 0xff;
change that and your model will work correctly!

How to convert image to zpl code for printing using zebra printer?

I want to print image along with some other texts through zebra printer from android application. I am able to create zpl code for text data but I am having to problem to create zpl code for image. The zpl do not supports base64 code. The image needs to be converted to hex ascii and print using ^GF command.
The raw data with both text and image is available on this Pastebin link, and can be viewed in labelary viewer.
Is there any image conversion process?

I solved the problem and I am posting the answer so that other people can take benefit from the solution. The bitmap image can be converted to zpl code using following converter class.
public class ZPLConverter {
private int blackLimit = 380;
private int total;
private int widthBytes;

public void setBlacknessLimitPercentage(int percentage) {

Example usage:
You need to convert the your image to bitmap, convert to monochrome image and do hex acii conversion. The generated zpl code can be checked at labelary viewer.
public class Utils {
public static String getZplCode(Bitmap bitmap, Boolean addHeaderFooter) {
ZPLConverter zp = new ZPLConverter();
zp.setCompressHex(true);
zp.setBlacknessLimitPercentage(50);
Bitmap grayBitmap = toGrayScale(bitmap);
return zp.convertFromImage(grayBitmap, addHeaderFooter);
}
public static Bitmap toGrayScale(Bitmap bmpOriginal) {
int width, height;
height = bmpOriginal.getHeight();
width = bmpOriginal.getWidth();
Bitmap grayScale = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(grayScale);
Paint paint = new Paint();
ColorMatrix cm = new ColorMatrix();
cm.setSaturation(0);
ColorMatrixColorFilter f = new ColorMatrixColorFilter(cm);
paint.setColorFilter(f);
c.drawBitmap(bmpOriginal, 0, 0, paint);
return grayScale;
}
}
The converter code has been referenced from here and added support for android use.

I know this is kind of done deal but I still struggle a lot with the current answer. I wanted to share my experience for those who might need it.
First of all,^GFA stands for hexadecial representation of the pixel but it has to be converted into readable text (ASCII). Here is an example :
Pixels white = 1, black = 1
1011 0100 translate into 0xB4
In the data section of ^GFA, you need to have B4 as data.
If we go with
Pixel line 1 : 1011 0100 1001 1100 = 0xBA 0x9C
Pixel line 2 : 0011 0110 0001 1111 = 0x36 0x1F
the resulting ZPL code will be :
^XA (needed to start a ZPL file)
^F10,0 (offsets 10 pixel horizontal, 0 pixel vertical)
^GFA,4,4,2,BA9C361F (4 is the total number of byte, 2 is the number of byte per line)
^F0^XZ (end of file)
Now, the interesting point. How to get to code that :
You need a gray-scale bitmap. You need pixel-wise access to the bitmap. In another words, an array containing integer which values varies from 0 to 255.
With that array you take each bunch of 8 pixels, convert it to hexadecimal value and then to text representation of these hexadecimals. Here is the c++ code made with Borland :
Graphics::TBitmap *imageFax = new Graphics::TBitmap();
unsigned char r;
unsigned char b;
ofstream outFile;
char listeHex[16];
int lineByteWidth;
int j;
int bytesCount = 0;
int widthHeight;
AnsiString testOut;
listeHex[0] = '0';
listeHex[1] = '1';
listeHex[2] = '2';
listeHex[3] = '3';
listeHex[4] = '4';
listeHex[5] = '5';
listeHex[6] = '6';
listeHex[7] = '7';
listeHex[8] = '8';
listeHex[9] = '9';
listeHex[10] = 'A';
listeHex[11] = 'B';
listeHex[12] = 'C';
listeHex[13] = 'D';
listeHex[14] = 'E';
listeHex[15] = 'F';
imageFax->Monochrome = true;
imageFax->PixelFormat = pf8bit;
imageFax->LoadFromFile("c:/testEtiquette/test.bmp"); //1200x300pixels bitmap test image
testOut = "c:/testEtiquette/outputfile.txt";
outFile.open(testOut.c_str());
imageFax->PixelFormat = pf8bit;
lineByteWidth = imageFax->Width/8;//Number of byte per line
widthHeight = lineByteWidth*imageFax->Height;//number of total byte to be written into the output file
testOut = "^XA^FO10,0^GFA,";
outFile << testOut.c_str() << widthHeight << ',' << widthHeight << ',' << lineByteWidth << ',' ;
for(int i = 0; i < imageFax->Height; i++)
{
unsigned char * pixel = (unsigned char *)imageFax->ScanLine[i];
bytesCount = 0;
b=0x00;
for(j = 0; j < imageFax->Width; j++)
{
//Here is the "switch" : what is not white (255) bit = 0, is black bit = 1.
//You can set your switch at whatever value you think is best. 0, 255 or anything between.
//I think 255 (white) is a good for my application
if(pixel[j] != 255)
{
b = b<<1;
//It is not white (hence black), we force value 1 into current position
b = b|0x01;
}
else
{
//Since it white, we move 1 bit to the left, pushing 0 into current position
b = b<<1;
b = b&0xFE;//Forcing a 0 in the current position
}
//If we've got a full byte (8-bits), we write it into the file
//This will lead into cutting off part of images that width is not a multiple of 8
if(j%8 == 7)
{
bytesCount++;
r = b;
r = r&0xF0; //Cleaning last digits
r=r>>4; //Moving the bits to the left 0xF0 => 0x0F
outFile << listeHex[r%16]; //Reaching into the conversion array listeHex, ASCII representation of hex value
r = listeHex[r%16]; //For debug only
r = b;
r = r&0x0F;//Cleaning first digits
outFile << listeHex[r%16];//Reaching into the conversion array listeHex, ASCII representation of hex value
r = listeHex[r%16]; //For debug only
b = 0x00; //Reseting for next Byte
}
}
}
testOut = "^F0^XZ";
outFile << testOut.c_str();
outFile.close();
delete imageFax;

Android Generate QR code and Barcode using Zxing

Code to generate Qr code using zxing is ---
It takes string data and the imageview This works just fine
private void generateQRCode_general(String data, ImageView img)throws WriterException {
com.google.zxing.Writer writer = new QRCodeWriter();
String finaldata = Uri.encode(data, "utf-8");
BitMatrix bm = writer.encode(finaldata, BarcodeFormat.QR_CODE,150, 150);
Bitmap ImageBitmap = Bitmap.createBitmap(150, 150,Config.ARGB_8888);
for (int i = 0; i < 150; i++) {//width
for (int j = 0; j < 150; j++) {//height
ImageBitmap.setPixel(i, j, bm.get(i, j) ? Color.BLACK: Color.WHITE);
}
}
if (ImageBitmap != null) {
qrcode.setImageBitmap(ImageBitmap);
} else {
Toast.makeText(getApplicationContext(), getResources().getString(R.string.userInputError),
Toast.LENGTH_SHORT).show();
}
}
Now my question is ,how to get bar code using the same library.i saw some files related to bar codes but i am not sure how to do it.
Since I want to generate the bar code within the application and not call any web service. Since i am already using zxing,no point in including itext and barbecue jars

Like Gaskoin told... MultiFormatWrite it worked :) here is the code.
com.google.zxing. MultiFormatWriter writer =new MultiFormatWriter();
String finaldata = Uri.encode(data, "utf-8");
BitMatrix bm = writer.encode(finaldata, BarcodeFormat.CODE_128,150, 150);
Bitmap ImageBitmap = Bitmap.createBitmap(180, 40,Config.ARGB_8888);
for (int i = 0; i < 180; i++) {//width
for (int j = 0; j < 40; j++) {//height
ImageBitmap.setPixel(i, j, bm.get(i, j) ? Color.BLACK: Color.WHITE);
}
}
if (ImageBitmap != null) {
qrcode.setImageBitmap(ImageBitmap);
} else {
Toast.makeText(getApplicationContext(), getResources().getString(R.string.userInputError),
Toast.LENGTH_SHORT).show();
}

I've tested the accepted answer to generate a Barcode but the output is blurry when used in a big ImageView. To get a high quality output, the width of the BitMatrix, the Bitmap and the final ImageView should be the same. But doing so using the accepted answer will make the Barcode generation really slow (2-3 seconds). This happens because
Bitmap.setPixel()
is a slow operation, and the accepted answer is doing intensive use of that operation (2 nested for loops).
To overcome this problem I've modified a little bit the Bitmap generation algorithm (only use it for Barcode generation) to make use of Bitmap.setPixels() which is much faster:
private Bitmap createBarcodeBitmap(String data, int width, int height) throws WriterException {
MultiFormatWriter writer = new MultiFormatWriter();
String finalData = Uri.encode(data);
// Use 1 as the height of the matrix as this is a 1D Barcode.
BitMatrix bm = writer.encode(finalData, BarcodeFormat.CODE_128, width, 1);
int bmWidth = bm.getWidth();
Bitmap imageBitmap = Bitmap.createBitmap(bmWidth, height, Config.ARGB_8888);
for (int i = 0; i < bmWidth; i++) {
// Paint columns of width 1
int[] column = new int[height];
Arrays.fill(column, bm.get(i, 0) ? Color.BLACK : Color.WHITE);
imageBitmap.setPixels(column, 0, 1, i, 0, 1, height);
}
return imageBitmap;
}
This approach is really fast even for really big outputs and generates a high quality bitmap.

You are using QRCodeWriter. If you want to write another type of code, use another Writer.
Check this MultiFormatWriter - it can write any type of bar or find specific writers here in subfolders (this is from zxing library)

There you go,
public static Bitmap createBarCode (String codeData, BarcodeFormat barcodeFormat, int codeHeight, int codeWidth) {
try {
Hashtable<EncodeHintType, ErrorCorrectionLevel> hintMap = new Hashtable<EncodeHintType, ErrorCorrectionLevel> ();
hintMap.put (EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.L);
Writer codeWriter;
if (barcodeFormat == BarcodeFormat.QR_CODE) {
codeWriter = new QRCodeWriter ();
} else if (barcodeFormat == BarcodeFormat.CODE_128) {
codeWriter = new Code128Writer ();
} else {
throw new RuntimeException ("Format Not supported.");
}
BitMatrix byteMatrix = codeWriter.encode (
codeData,

Of course you can support as many BarcodeFormats as you want, just change the constructor here :
Writer codeWriter;
if (barcodeFormat == BarcodeFormat.QR_CODE) {
codeWriter = new QRCodeWriter ();
} else if (barcodeFormat == BarcodeFormat.CODE_128) {
codeWriter = new Code128Writer ();
} else {
throw new RuntimeException ("Format Not supported.");
}

try this code
Context context = getActivity();
Intent intent = new Intent("com.google.zxing.client.android.ENCODE");
intent.putExtra("ENCODE_TYPE", Text);
intent.putExtra("ENCODE_DATA", "12345678901");
intent.putExtra("ENCODE_FORMAT", "UPC_A");
startActivity(intent);
hope this helps you.
