Here is how it can be done with C# .NET without using the Win32API within the scope of a .NET application. The Win32API approach retains the default printer After the application is closed.
下面是如何在 C# .NET 中完成它而不使用 .NET 应用程序范围内的 Win32API。Win32API 方法在应用程序关闭后保留默认打印机。
using System.Drawing.Printing;
namespace MyNamespace
{
public class MyPrintManager
{
public static PrinterSettings MyPrinterSettings = new PrinterSettings();
public static string Default_PrinterName
{
get
{
return MyPrinterSettings.PrinterName;
}
set
{
MyPrinterSettings.DefaultPageSettings.PrinterSettings.PrinterName = value;
MyPrinterSettings.PrinterName = value;
}
}
}
}

Step 1: Paste the following code anywhere in your .cs file
第 1 步：将以下代码粘贴到 .cs 文件中的任何位置
public static class PrinterClass
{
[DllImport("winspool.drv", CharSet = CharSet.Auto, SetLastError = true)]
public static extern bool SetDefaultPrinter(string Printer);
}
Step 2: Add the neccesary namespace i.e
第 2 步：添加必要的命名空间，即
using System.Runtime.InteropServices;
Step 3: Use the following function to set desired printer as default printer.
步骤 3：使用以下功能将所需的打印机设置为默认打印机。
PrinterClass.SetDefaultPrinter("Paste your desired Printer Name here");
Step 4: To get the list of all printers attached to your PC, you can use this code.
第 4 步：要获取连接到 PC 的所有打印机的列表，您可以使用此代码。
private void FillListBox()
{
foreach (var p in PrinterSettings.InstalledPrinters)
{
cmbdefaultPrinter.Properties.Items.Add(p);
}
}
//Here cmbdefaultPrinter is a combobox, you can fill the values into a list.
Namespaces required for the above code are:
上述代码所需的命名空间是：
using System.Drawing.Printing;
using System.Runtime.InteropServices;
