Please help me! when i changed to android studio debugger says : * What went wrong:
Execution failed for task ':printama:compileDebugJavaWithJavac'.

Compilation failed; see the compiler error output for details.

Can't print arabic text

How can I return as a for loop?

When i was clicked save button .

Hi, I just mailed you about this issue.

You set PRINTER_WIDTH = 384 (which is fixed). That doesn't care about the actual printer paper width. Instead of that, can't we detect printer paper size from socket data? or you can add a paper size option on choose printer dialog. So, if we set 58mm/80mm/custom width, then it will be used as printer width throughout the app for that selected printer.

I am testing this library on JP-Q2i POS Terminal PDA (Embedded printer is configured as Bluetooth device)
but I cannot print a text.

Printama.with(this).connect(new Printama.OnConnected() {
                    @Override
                    public void onConnected(Printama printama) {
                        printama.printText("TEST");
                    }
                });

Library connect with MPT-II but not start a print

How its happened

Before this happened, I tried to print an image (logo) with several text below it, and its works verry well with no issue, but after I added QR Code (Bitmap) to be printed with, the logo just printed half and half more becomes unreadable character (image below)

Here it is the code that i used for :

val logo = Printama.getBitmapFromVector(activity, R.drawable.logo_black)
val nota = "Some Text"
Printama.with(activity).connect({ printama: Printama ->
      printama.printImage(logo, 200)
      printama.addNewLine()
      printama.printTextln(Printama.CENTER, "Title Text")
      printama.setNormalText()
      printama.printTextln(
          Printama.CENTER,
          "Some Text"
      )
    printama.printDashedLine()

    val writer = QRCodeWriter()
    val bitMatrix = writer.encode(nota, BarcodeFormat.QR_CODE, 300, 300)
    val width = bitMatrix.width
    val height = bitMatrix.height
    val bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565)
    for (x in 0 until width) {
        for (y in 0 until height) {
            bitmap.setPixel(x, y, if (bitMatrix.get(x, y)) Color.BLACK else Color.WHITE)
        }
    }

    bitmap?.let {
        printama.printImage(it)
    }

    printama.addNewLine()
    printama.feedPaper()
    printama.close()
}) { message: String? -> activity.toast(message) }

Hi, I'm just wondering how to Set the DPI and Font Style

I download a apk "RawBT" it can change the font to True Type Font and DPI to 304

when i try to print full bitmap image in 58mm printer
print Chinese char
