Printing in arabic is not working.

[tawfek]

I'm trying to print Arabic text on a POS printer.
i have tried both "star" and "Epson" types
and i have tested on both wpc1256_arabic and pc864_arabic .

Printing in English is working fine. printing images using <Image src.. /> also works fine.
but when I try to print an Arabic text, it shows an unknown character. (not ???)

Printer function:

  const printer = async () => {
 
    if (!printerState) {
     // connecting to printer
       ....
           setPrinterState(() => characteristic);
       ....
    }

    printing();
  };

Printing function

  const printing = async () => {
    const data = await render(
      <Printer type="star" width={88} characterSet="wpc1256_arabic">
        <Text>مرحبا بك في رياكت</Text>
      </Printer>
    );
    // Print the data in chunks
    await printChunks(printerState, data);
  };

printChunks function:

  const sendChunk = async (printerState, chunk) => {
    try {
      await printerState.writeValueWithResponse(chunk);
    } catch (error) {
      console.error(`Error sending data chunk: ${error}`);
      throw error;
    }
  };

Printer trigger:

  <Button type="primary" onClick={printer}>
        PRINT
  </Button>

hi tawfek are u found any solution for handle text and !

Hi @mustafa-altai77, unfortunately no.
but there is something I didn't try which is converting it to an image and printing it.
I think this would work but it will take more time to develop (which I didn't have).

Thanks.

This can happen due to a mismatch between the ESC/POS character set and the iconv-lite encoding options. (I haven't tested all other languages.)

You can specify a custom encoder in the <Printer />. Can you tell me the encoding that is output normally by inserting the custom encoder?

<Printer encoder={(text, charSet) => ...}>
</Printer>
