通过RJ11插入打印机。

如何在销售时从我的C＃POS应用程序中打开此抽屉。我打印机从打印机首选项中检查抽屉打印后打开工作正常。



我尝试了什么：



我尝试编写代码这里它给了我错误端口关闭。所以我改为：

via RJ11 plugged into Printer.
How can I open this drawer from my C# POS application when sale is made. I checked drawer from Printer Preference to open after printing it works fine.

What I have tried:

I tried writing code as stated HERE It gave me error port is closed . So I changed it to :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO.Ports;
namespace cashdrawertest
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private SerialPort serialPort1 = new SerialPort();

        public void OpenPort()
        {
            //serialPort1.PortName = "COM1";
            serialPort1.PortName = "ESDPRT001";
            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;
            try
            {
                serialPort1.Open();
            }
            catch (Exception ex)
            {
                serialPort1.Close();
                serialPort1.Open();
            }
//            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));
        }
        private void button1_Click(object sender, EventArgs e)
        {
            OpenDrawer();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

            serialPort1.PortName = "COM1";
            //serialPort1.PortName = "ESDPRT001";
            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;
            try
            {
                serialPort1.Open();
            }
            catch (Exception ex)
            {
                serialPort1.Close();
                serialPort1.Open();
            }
        }
    }
}

我在打印机属性下检查了端口有ESDPRT001用于

I checked Port under printer properties it has ESDPRT001 for

同样，它说同样的东西是封闭的。所以请帮忙。谢谢

Again it says same thing Port is Closed. So please help. Thanks

推荐答案

在 OpenDrawer 方法的第一行放置一个断点，然后在调试器中运行你的应用程序。断点被击中时检查SerialPort对象的状况。



但是......两件事：

1）复制代码时从互联网上随机选择，考虑你在做什么是个好主意 - 你没有这样做，或者你不会在加载中重复相同的代码事件处理程序和您从未调用的 OpenPort 方法。

2）当您从Internet复制代码时，您可能希望将其全部复制 - 并在某个时候调用 InitializePrinter 方法。

3）当你从互联网上复制代码时，考虑它并考虑它是一个非常好的主意。检查您尝试使用的COM端口实际上是否适合您的打印机 - COM1可能不是正确的端口。在开始编写代码之前，始终使用终端程序（如HyperTerminal）证明通信，以确保在添加另一层混淆之前一切正常。



该代码是......呃......很穷我知道，我知道 - 你没有写。但如果它无法打开，只需再试一次是一种做任何事情的糟糕方式......

Put a breakpoint on the first line in your OpenDrawer method, and run your app in the debugger. Check the condition of the SerialPort object when the breakpoint gets hit.

But ... two things:
1) When you copy code at random from the internet, it's a good idea to think about what you are doing - you aren't doing that or you wouldn't have the same code repeated in your Load event handler and your OpenPort method that you never call.
2) When you copy code from the internet, you might want to copy it all - and call the InitializePrinter method at some point.
3) When you copy code from the internet, it's a very good idea to think about it and check that the COM port you are trying to use is in fact the right one for your printer - COM1 may not be the right port. Always prove communications using a terminal program such as HyperTerminal before you even start to write code to make sure that everything is working before adding another layer of confusion.

That code is ... um ... poor. I know, I know - you didn't write it. But "if it fails to open, just try again" is a poor way to do anything ...
