所以我一直在为蓝牙打印机编写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%20user%20manual / SP-MP-300-Technical% 20Manual.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);
mService实际写入数据的位置。我得到的最好输出是0█0█0,00,000100,内many,在连续多次发送数据之后。
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。
我也看过以下地方:

Where can I find a "ESC/POS" Epson Barcode Test Program?
答案 0 :(得分:5)
好吧事实证明,在ESC / POS中,打印机实际上为您计算了一些数据。我不应该把检查字节(实际条形码的最后一位数字)放在我发送到打印件的数据中。
当然,我的文档缺少所有< =符号并没有帮助。我最终使用此文档寻求帮助:http://content.epson.de/fileadmin/content/files/RSD/downloads/escpos.pdf
我仍然在进行二维码打印,但我确信我的问题有点类似。
