打印购物小票可以通过多种编程语言和方法实现。以下是几种常见的方法:

1. 使用C和Windows Forms

```csharp

using System;

using System.Data;

using System.Windows.Forms;

namespace ShoppingReceiptPrinter

{

public partial class Form1 : Form

{

private DataGridView dataGridView1;

private TextBox textBox3;

public Form1()

{

InitializeComponent();

}

private void jzPrint()

{

if (dataGridView1.Rows.Count == 0)

{

MessageBox.Show("没有购物数据,无法收银和打印!");

return;

}

if (textBox3.Text.Trim() == "")

{

MessageBox.Show("没有输入付款金额,无法收银打印!");

return;

}

string operuser = "露天其"; // 收银员的名称,实际修改时,应该成登录者的名字即可

// 第一步,首先把这项订单写入数据库的表中

string day = DateTime.Now.ToString("yyyyMMdd");

string time = DateTime.Now.ToString();

// 第三步,进行打印

PrintDocument printDoc = new PrintDocument();

printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage);

printDoc.Print();

}

private void printDoc_PrintPage(object sender, PrintPageEventArgs e)

{

e.Graphics.DrawString("收银员: " + operuser, this.Font, Brushes.Black, 10, 10);

e.Graphics.DrawString("日期: " + day, this.Font, Brushes.Black, 10, 30);

e.Graphics.DrawString("时间: " + time, this.Font, Brushes.Black, 10, 50);

foreach (DataGridViewRow row in dataGridView1.Rows)

{

e.Graphics.DrawString(row.Cells.Value.ToString() + ":", this.Font, Brushes.Black, 10, 70 + row.Index * 20);

e.Graphics.DrawString(row.Cells.Value.ToString(), this.Font, Brushes.Black, 100, 70 + row.Index * 20);

e.Graphics.DrawString(row.Cells.Value.ToString(), this.Font, Brushes.Black, 150, 70 + row.Index * 20);

e.Graphics.DrawString(row.Cells.Value.ToString(), this.Font, Brushes.Black, 200, 70 + row.Index * 20);

}

e.Graphics.DrawString("合计: " + textBox3.Text, this.Font, Brushes.Black, 10, 400);

}

}

}

```

2. 使用Python
