String voucherNameWithValueMessage = 'ليبيانا 5 دينار'; blueThermalPrinter.printCustom( voucherNameWithValueMessage, _onlyBoldText, _alignCenterText, charset: 'windows-1256');

me too it's not working for me
did you solve it ? if so
I really need help

[fatimaown93]

windows-1256 worked with me

how did you did it ?!

[ebrahimmansur]

still nothing....

[fatimaown93]

still nothing....

actually I find a way but it's really twisted 🤣

I used canvas textpainter and then convert it to an image
then I used the function printImageBytes
It works but there was a problem the function printimage has a fixed height for the image [200px - 250px]. I will try to make it more than one image on sunday.

not an efficient solution ....i thought about make it an pdf then printing it as an image before.....still not really a solution 😂...so still waiting on @kreemov to show me if it really works.

What's the result of using utf-8 as the charset?

Can I ask the make/model of the printer?

[ebrahimmansur]

that is the problem we don’t have constraint on what printer the merchant uses, we only provide the connection and printing functionality....if we did we could have used the printer's sdk...😁

I see 😅 the only other thing I can suggest is try print through a quick Node.js script with something like https://www.npmjs.com/package/node-thermal-printer that's known to support Arabic - if it works with that then it confirms it's an issue with this plugin and not the printer

[ebrahimmansur]

Thanks ...and also thanks a lot for the support ✌️ ... i appreciate the time .......can’t with for the next space ...it’s seems my issue with the "multi package" was not fully understood because of its complexity and with out having visual representation 😅😭

Go to the device POS settings, and on print settings, set printing with UTF-8.

If the above method doesn't work, try the next method (which is printing images as text).

Solution inspired from @fatimaown93.

You can convert the widget into an image (using Screenshot) and print it:

Here is the Widget:

Screenshot(
    controller: screenshotController,
    child: Container(
      width: 190,
      decoration: BoxDecoration(
          border: Border.all(color: Colors.black),
        color: Colors.white,
      ),
      // color: Colors.white,
      child: Column(
        children: [
          Row(
            children: [
              Text(
                'أهلاً وسهلاً',
                style: TextStyle(
                  color: Colors.black,
                ),
                textAlign: TextAlign.right,
              ),
              Spacer(),
              Text(
                'شكو ماكو؟',
                style: TextStyle(
                  color: Colors.black,
                ),
              ),
            ],
          ),
  
        ],
      ),
    ),
  ),

The widget is converted into image of Uint8List:

var imageTextRawUint8List = await screenshotController.capture() ?? Uint8List(0);

Then, print the image bytes:

 bluetooth.printImageBytes(imageTextRawUint8List);

Thanks so much @bluemix ,but I have already thought about it and implemented it if you have seen the conversion between me and @fatimaown93, but I want is an efficient solution , I wish if there was a way to convert codepage to utf-8 command as binary message to the thermal printer. Im still trying to test some things , I will keep you posted if I came with a better solution (I don't want to depend on a package not made for this problem and bound/scoped to a UI logic that can change over time ) .

windows-1256

how? can u share the code please
or correct if i am wrong
Uint8List encoded =
await CharsetConverter.encode('windows-1256', message.toString());
printer.textEncoded(encoded);

[bluemix]

you have to go the printer settings menu (Android settings) and set the encoding to utf-8 or windows-1256

[devmuaz]

Changing the printer settings (can be found in the android settings) worked for me, I set it to UTF-8 and now it's printing Arabic characters!
Thanks @bluemix 👏

[blitzlepe]

Can you share the path of file(to) to edit?

[devmuaz]

@blitzlepe It's in the system settings, there must be a section called Printer where you can change the encoding to UTF-8
