所以我一直在为蓝牙打印机编写一个Android应用程序,我已经意识到这实际上是ESC / POS标准：http://nicholas.piasecki.name/blog/wp-content/uploads/2009/12/ESC-POS-Command-Guide.pdf

现在我用于打印机的文档是这些命令的有限子集,可在此处找到：https://dl.dropboxusercontent.com/u/88265006/%E4%BA%A7%E5%93%81/Printer的用户手册/ SP-MP-300-技术手册.pdf

        private void initPrinter() {
            byte[] init = new byte[2];
            init[0] = 0x1B;
            init[1] = 0x40;
            mService.write(init);
        }
        private void printText(String message){
            byte[] send;
            try{
                send = message.getBytes("UTF8");
            }
            catch(UnsupportedEncodingException e){
                send = "Error".getBytes();
            }
            initPrinter();
            mService.write(send);
        }

我可以连接到打印机,用“ESC @”命令初始化它,我可以用上面的命令编写,但我似乎无法获得任何条形码的任何“视觉”效果.这是我尝试使用1D EAN13代码(0000000000000)：

        byte[] height = new byte[3];
        height[0] = 0x1D;
        height[1] = 0x68;
        height[2] = (byte)30;
        //height[3] = 0;
        byte[] width = new byte[3];
        width[0] = 0x1D;
        width[1] = 0x77;
        width[2] = (byte)3;
        byte[] textPos = new byte[3];
        textPos[0] = 0x1D;
        textPos[1] = 0x48;
        textPos[2] = (byte)2;
        byte[] level = new byte[3];
        level[0] = 0x1D;
        level[1] = 0x51;
        level[2] = (byte)32;
        byte[] code = new byte[18];
        code[0] = 0x1D;
        code[1] = 0x6B;
        code[2] = 0x02;
        code[3] = 0x0D;
        code[4] = 0x30;//1
        code[5] = 0x30;//2
        code[6] = 0x30;//3
        code[7] = 0x30;//4
        code[8] = 0x30;//5
        code[9] = 0x30;//6
        code[10] = 0x30;//7
        code[11] = 0x30;//8
        code[12] = 0x30;//9
        code[13] = 0x30;//10
        code[14] = 0x30;//11
        code[15] = 0x30;//12
        code[16] = 0x30;//13
        code[17] = 0x00;//end
        mService.write(height);
        mService.write(width);
        mService.write(textPos);
        mService.write(level);
        mService.write(code);

其中mService实际写入数据.我得到的最好输出是0█0█0,00,00100,如果连续多次发送数据.

如果我在多次发送后删除最后的结束字节,我得到14 0,我也尝试在高度,宽度,textPosition和级别数组中添加结尾0,没有任何影响.

我也看了以下几个地方：
