Arabic String not work with thermal printer

[iman2420]

I use this function to add Persian text :

.setText("سلام : HELLO")
.setEmphasizedMode(DefaultPrinter.EMPHASIZED_MODE_BOLD) //Bold or normal
.setFontSize(DefaultPrinter.FONT_SIZE_NORMAL)
.setUnderlined(DefaultPrinter.UNDERLINED_MODE_OFF) // Underline on/off
.setCharacterCode(byte) // Character code to support languages
.setLineSpacing(DefaultPrinter.LINE_SPACING_30)
.setNewLinesAfter(1)
printableList.add(printable.build())```

But only some incomprehensible text is printed.

@iman2420 Finally I was able to fix this by passing a custom converter, it was already built with the library ArabicConverter() like this .setCustomConverter(ArabicConverter()) It is worth mentioning that CP864 codepage value might be different from printer company to another, CHARCODE_ARABIC_CP864 in the library equals to 0x0E, but with my printer company it was 22 inside their codepage table so you might need to check your printer documentation, then pass the custom character code like this .setCharacterCode(22)

CodePage is a hex number, you should find something called CodePage Table in your printer company website or documentation so just pass these two lines with your TextPrintable builder

.setCharacterCode(22)
.setCustomConverter(ArabicConverter())

Are you trying to print Arabic string? .setCharacterCode(22) will only works with my printer company, you should find the correct codepage for your printer Did you try the default CP864 codepage ?
