Android蓝牙打印机例子

上一篇是佳博网络打印机的，这一篇是关于蓝牙（不是低功耗4.0）打印机的例子。

检查打印机纸的状态：

/**
	 * 佳博蓝牙打印机，检查纸的状态：
	 * 当接收状态为18时，表示蓝牙打印机是正常状态；接收状态为114(无纸)或114(没关盖)时，表示不正常状态
	 */
	public int doCheckJiaboPaperState() {
		/**1：正常，0：异常，-1：链接失败*/
		int flag = 0;
		try {
			InputStream bis = bluetoothSocket.getInputStream(); 
			outputStream.write(BlueThPrintInfo.stateBype);
			outputStream.flush();
			int tmp = bis.read();
			if (tmp == 18) {
				flag = 1;
			} else {
				flag = 0;
			}
		} catch (Exception e) {
			flag = -1;
			e.printStackTrace();
		}
		return flag;
	}

剩下的步骤和上一篇Android网络打印机一样。这里就不一一说明了。
