在C＃VS 2013中从DataGridView打印POS [英] POS Printing from DataGridView in C# VS 2013

问题描述

您好，我正在为服装展厅开发POS应用程序。设计部分完成，一切正常。现在我需要打印。我必须打印到POS打印机连接到运行该软件的计算机的收据，我想打印DataGridView表中显示的项目，格式就像我在模拟图像文件中附加的那样。

模拟图像收据： http://img247.imagevenue.com/img.php?image=51740_Slip02_122_105lo.jpg [ ^ ]



现在的问题是我对POS Printi的了解不多来自DataGridView Table或类似的东西。

任何打印类似这样或任何相关指南的教程都会非常感激。

Hello, I am in development of a POS Application for a Garments Showroom. The design part is done and Everything works fine. Now I need to print. I have to print to a money receipt with a POS Printer connected to the computer running the software and I wanted to print the Items shown in the DataGridView Table in a format like I have attached in the simulated Image file.

A Simulated Image Receipt: http://img247.imagevenue.com/img.php?image=51740_Slip02_122_105lo.jpg[^]

Now the problem is I don't know that much about POS Printing from DataGridView Table or something like this.
Any tutorial to print something like this or any related guideline would be much appreciated.

推荐答案

您只需创建具有相同图像收据设计的表单。然后将数据传递给表单打印表格如：

You only have to create a form with the same design of image receipt. Then pass the data to the form print the form like:

private PrintDocument printDocument1 = new PrintDocument();

public Form1()
{
    InitializeComponents();
    printDocument1.PrintPage += new PrintPageEventHandler(printDocument1_PrintPage);
    this.Controls.Add(printButton);
    CaptureScreen();
    printDocument1.Print();
}


Bitmap memoryImage;

private void CaptureScreen()
{
    Graphics myGraphics = this.CreateGraphics();
    Size s = this.Size;
    memoryImage = new Bitmap(s.Width, s.Height, myGraphics);
    Graphics memoryGraphics = Graphics.FromImage(memoryImage);
    memoryGraphics.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, s);
}

private void printDocument1_PrintPage(System.Object sender,
       System.Drawing.Printing.PrintPageEventArgs e)
{
    e.Graphics.DrawImage(memoryImage, 0, 0);
}

我不知道你的数据是什么，你可以用不同的方式传递数据。您可以向我提供源代码，我可以提供更好的帮助。

I don't know what is your data and you can pass the data using different ways. You may provide me the source code and I may be able to help better.

大多数POS打印机都支持由EPSON开发的ESC / POS打印机命令。您必须学习ESC / POS，然后生成要发送到打印机的命令。您可以使用此代码从.NET应用程序发送原始打印机命令。

Most POS printers do support ESC/POS printer commands which was developed by EPSON. You have to learn ESC/POS and then generate the commands to be sent to the printer. You can use this code to send raw printer commands from your .NET app.
