盒子论坛 v2.1

现在有三种方式

1.移动端 wifi 连到windows电脑上的共享打印机，或自带共享服务器的打印机

2.移动端用蓝牙方式连接打印机

3.移动端通过usb转接线直连打印机

我看了一下 xe10.1带的例子，BlueChat
想下当年也是在dos 用c写过类似的的这种控制pos58小票打印机打小票
所用的方法类似
TEncoding.UTF8.GetBytes(FStringsToWrite[I]);  //这里是写

还有一个TReadTHread 去读

具体那种命令字符控制打印机，要用到pos小票打印机的sdk文档，

.procedure TWriteThread.Execute;
var
  I: Integer;
  LFailed: Boolean;
  LBytesToSend: TBytes;
  LClientSocket: TBluetoothSocket;
begin
  inherited;
  While not Terminated do
  begin
    if FStringsToWrite.Count > 0 then
    begin
      FDevice.GetServices;
      LClientSocket := FDevice.CreateClientSocket(FGUID, False);
      try
        LClientSocket.Connect;
//        if LClientSocket.Connected then
        begin
          TMonitor.Enter(FLock);
          LFailed := False;
          try
          for I := 0 to FStringsToWrite.Count - 1 do
          begin
          try
          LBytesToSend := TEncoding.UTF8.GetBytes(FStringsToWrite[I]);
          LClientSocket.SendData(LBytesToSend);
          if Assigned(FOnTextSent) then
          FOnTextSent(Self, FStringsToWrite[I], FName);
          except
          LFailed := True;
          Break;
          end;
          end;
          if not LFailed then
          FStringsToWrite.Clear
          else if Assigned(FOnTextSent) then
          FOnTextSent(Self, FStringsToWrite[I] + ' "failed to send"', FName);
          finally
          TMonitor.Exit(FLock);
          end;
        end;
      finally
        LClientSocket.Close;
        FreeAndNil(LClientSocket);
      end;
    end;
    Sleep(500);
  end;
end;

3楼：

最简单的方法，手机写入数据库打印记录，电脑上写个小程序读取记录，然后打印。
