谢谢 我试用了下 现在打印2维码 居然可以了 什么个情况 兄弟我把分全给你吧  谢谢你了 如果你方便的话 把你的完整例子发下我看看 [email protected] 

Answer 3

怎么使用fnthex32.dll打印二维码呀，真是无头绪，拜托LZ帮帮忙，指导一下吧~~~~~~~~~~~~

Answer 4

是斑马打印机来的，不知道怎么使用FNTHEX32.DLL来打印二维码，现在是只能打印中文字呢~~~

longteng670603753很厉害，我亲自测试没问，解决了几天来一直为解决的中文打印问题，多谢了！

Answer 6

可以给我传一份完整的代码吗？我这边还是没有调试出来。ConverFontToImageResult pinming = getFontText("打印中文内容", "黑体", Orientation.Orien0,55,20,true, false);
            Writer.WriteLine(pinming.Instruction.ToString() + pinming.ImageName.ToString() + "," + pinming.TotalSize.ToString() + "," + pinming.RowSize.ToString() + ",");
            Writer.WriteLine(pinming.ImageData.ToString());
            Writer.WriteLine("^FO225,220^XG" + pinming.ImageName.ToString() + ",1,1^FS");  //打印品名
上面这段代码是什么意思，怎么发送给打印机！！！
