我正在为我的“Woosim S30 / 40”打印机开发一个Android应用程序。打印机 与我的手机配对,代码中没有例外。但是当我在蓝牙插座上写字时,只是数据指示灯略微闪烁,没有任何反应(没有打印。)我尝试了很多代码来自堆栈流量和应用程序形成谷歌商店,但同样的事情发生。 打印机样本纸显示如下设置
打印事件代码:(从堆栈溢出使用)
mPrint = (Button) findViewById(R.id.mPrint);
mPrint.setOnClickListener(new View.OnClickListener() {
public void onClick(View mView) {
Thread t = new Thread() {
public void run() {
try {
OutputStream os = mBluetoothSocket.getOutputStream();
String BILL = "";
BILL = "\nInvoice No: ABCDEF28060000005" + " " + "04-08-2011\n";
BILL = BILL + "-----------------------------------------";
BILL = BILL + "\n\n";
BILL = BILL + "Total Qty:" + " " + "2.0\n";
BILL = BILL + "Total Value:" + " " + "17625.0\n";
BILL = BILL + "-----------------------------------------\n";
os.write(BILL.getBytes());
// Setting height
int gs = 29;
os.write(intToByteArray(gs));
int h = 104;
os.write(intToByteArray(h));
int n = 162;
os.write(intToByteArray(n));
// Setting Width
int gs_width = 29;
os.write(intToByteArray(gs_width));
int w = 119;
os.write(intToByteArray(w));
int n_width = 2;
os.write(intToByteArray(n_width));
// Print BarCode
int gs1 = 29;
os.write(intToByteArray(gs1));
int k = 107;
os.write(intToByteArray(k));
int m = 73;
os.write(intToByteArray(m));
String barCodeVal = "ASDFC028060000005";// "HELLO12345678912345012";
System.out.println("Barcode Length : " + barCodeVal.length());
int n1 = barCodeVal.length();
os.write(intToByteArray(n1));
for (int i = 0; i < barCodeVal.length(); i++) {
os.write((barCodeVal.charAt(i) + "").getBytes());
}
} catch (Exception e) {
Log.e("Main", "Exe ", e);
}
}
};
t.start();
}
});
