爱普生TM-T88V打印机抽屉踢

Question

我的客户为其 POS 系统购买了一个新的现金抽屉。
现金抽屉的特点如下：

Model: D41SRB
SKU: D41SRB
Electronic Cash Drawer Black 16",
Roller, 24V Epson STD RJ11, Stainless front
5 Bill/5 Coin
1mm steel case
Two extra brackets inside top of case for added durability`

它已连接到收据打印机 EPSON TM-T88V Receipt。我需要在我的 C# 应用程序中单击按钮打开此抽屉，但是当我将抽屉设置为在从打印机首选项打印后打开时，它可以工作。所以，我确定它连接正常。我需要类似于但在 C# 中的东西。所以请帮忙

Answer 1

要打开TM-T88系列的抽屉，需要通过串口或网口连接。

下面的命令序列是我使用的。这确实是旧代码，但它应该可以完成工作。您必须在执行任何其他操作之前打开端口并初始化打印机，所以它也在那里。

private SerialPort serialPort1 = new SerialPort();

public void OpenPort()
{
    serialPort1.PortName = "COM1";
    serialPort1.Encoding = Encoding.ASCII;
    serialPort1.BaudRate = 38400;
    serialPort1.Parity = System.IO.Ports.Parity.None;
    serialPort1.DataBits = 8;
    serialPort1.StopBits = System.IO.Ports.StopBits.One;
    serialPort1.DtrEnable = true;
    serialPort1.Open();
}

public void InitializePrinter()
{
    serialPort1.Write(Char.ConvertFromUtf32(27) + char.ConvertFromUtf32(64));
}

public void OpenDrawer()
{
    serialPort1.Write(char.ConvertFromUtf32(27) +
       char.ConvertFromUtf32(112) + 
       char.ConvertFromUtf32(0) +
       char.ConvertFromUtf32(5) + 
       char.ConvertFromUtf32(5));
}

Answer 2

我能够解决我使用过的问题

RawPrinterHelper.SendStringToPrinter("EPSON TM-T88V Receipt", System.Text.ASCIIEncoding.ASCII.GetString(new byte[] { 27, 112, 48, 55, 121 }));

从 http://keyhut.com/popopen.htm

得到这个抽屉代码

这是我的全部代码：

            public string pOutputFile;
            [MarshalAs(UnmanagedType.LPStr)]

        }
        [DllImport("winspool.Drv", EntryPoint = "OpenPrinterA", SetLastError = true, CharSet = CharSet.Unicode, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]

            // Open the printer.
            if (OpenPrinter(szPrinterName.Normalize(), out hPrinter, IntPtr.Zero))
            {
                // Start a document.
                if (StartDocPrinter(hPrinter, 1, di))
                {
                    // Start a page.
                    if (StartPagePrinter(hPrinter))
                    {
                        // Write your bytes.
                        bSuccess = WritePrinter(hPrinter, pBytes, dwCount, out dwWritten);

                }
                ClosePrinter(hPrinter);
            }
            // If you did not succeed, GetLastError may give more information
            // about why not.
            if (bSuccess == false)
            {
                dwError = Marshal.GetLastWin32Error();
            }
            return bSuccess;
        }

        public static bool SendFileToPrinter(string szPrinterName, string szFileName)
        {
            // Open the file.
            FileStream fs = new FileStream(szFileName, FileMode.Open);
            // Create a BinaryReader on the file.
            BinaryReader br = new BinaryReader(fs);
            // Dim an array of bytes big enough to hold the file's contents.
            Byte[] bytes = new Byte[fs.Length];
            bool bSuccess = false;
            // Your unmanaged pointer.
            IntPtr pUnmanagedBytes = new IntPtr(0);
            int nLength;

            nLength = Convert.ToInt32(fs.Length);
            // Read the contents of the file into the array.
            bytes = br.ReadBytes(nLength);
            // Allocate some unmanaged memory for those bytes.
            pUnmanagedBytes = Marshal.AllocCoTaskMem(nLength);
            // Copy the managed byte array into the unmanaged array.
            Marshal.Copy(bytes, 0, pUnmanagedBytes, nLength);
            // Send the unmanaged bytes to the printer.

            // the string to ANSI text.

 private void button1_Click(object sender, EventArgs e)
    {
        RawPrinterHelper.SendStringToPrinter("EPSON TM-T88V Receipt", System.Text.ASCIIEncoding.ASCII.GetString(new byte[] { 27, 112, 48, 55, 121 }));
    }

点击 button1 之后，它会启动抽屉。

Answer 3

假设您的串行端口名为 "port"。

只需使用：port.writeLine("\x10\x14\x01\x00\x08"); // 对于现金抽屉 0

只需使用：port.writeLine("\x10\x14\x01\x01\x08"); // 对于现金抽屉 1

因为打印机可以与 2 个现金抽屉通信。

命令：

ASCII DCE DC4 n m t

十六进制 10 14 n m t

十进制 16 20 n m t

其中 n = 1，m = 0 或 1（钱箱编号），t <= 1，t <=8
