How do I set the windows default printer in C#.NET?
回答1:
Using the SetDefaultPrinter Windows API.
Here's how to pInvoke that.
回答2:
using System;
using System.Drawing.Printing;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
private void listAllPrinters()
{
foreach (var item in PrinterSettings.InstalledPrinters)
{
this.listBox1.Items.Add(item.ToString());
}
}
private void listBox1_SelectedValueChanged(object sender, EventArgs e)
{
string pname = this.listBox1.SelectedItem.ToString();
myPrinters.SetDefaultPrinter(pname);
}
public Form1()
{
InitializeComponent();
listAllPrinters();
}
}
public static class myPrinters
{
[DllImport("winspool.drv", CharSet = CharSet.Auto, SetLastError = true)]
public static extern bool SetDefaultPrinter(string Name);
}
}

Step 1: Paste the following code anywhere in your .cs file
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
using System.Runtime.InteropServices;
Step 3: Use the following function to set desired printer as default printer.
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.
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:
using System.Drawing.Printing;
using System.Runtime.InteropServices;

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.
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;
}
}
}
}

You can use WMI as well.
