我有一个 Bixolon SRP-330II PosPrinter，我正在使用它的官方 javascript SDK。其中有更改字符集的功能，但我测试了27哪些是阿拉伯语Farsi，哪些是阿拉伯语。仍然只打印英文字符就可以了，其他字符就可以了。有什么帮助吗？1256856?????

这是我的代码，它是其文档示例的简化版本

        var strSubmit = getPosData();

        console.log(strSubmit);

        issueID++;
        requestPrint('Printer1', strSubmit, viewResult);

        return true;
