要生成内置Windows测试页,您还可以对PrintUI.dll使用p / invoke。这是一个简单的类,可以让你这样做:
public static class PrintTestPageHelper
{
[DllImport("printui.dll", SetLastError = true, CharSet = CharSet.Unicode)]
private static extern void PrintUIEntryW(IntPtr hwnd,
IntPtr hinst, string lpszCmdLine, int nCmdShow);
/// <summary>
/// Print a Windows test page.
/// </summary>
/// <param name="printerName">
/// Format: \\Server\printer name, for example:
/// \\myserver\sap3
/// </param>
public static void Print(string printerName)
{
var printParams = string.Format(@"/k /n{0}", printerName);
PrintUIEntryW(IntPtr.Zero, IntPtr.Zero, printParams, 0);
}
}
public class Program
{
static void Main(string[] args)
{
PrintTestPageHelper.Print(@"\\printserver.code4life.com\sap3");
Console.WriteLine("Press enter to exit.");
Console.ReadLine();
}
}

使用WMI,特别是PrintTestPage类的Win32_Printer方法。
有关如何从C#执行WMI方法的信息,请参阅此MSDN文章:How To: Execute a Method

正如ho1所说,WMI可以容纳你:
ManagementClass processClass = new ManagementClass("Win32_Printer");
ManagementBaseObject outP = processClass.InvokeMethod("PrintTestPage", null);
if (Convert.ToUInt32(outP["ReturnValue"]) != 0)
{
MessageBox.Show("Failed to print test page.");
}
每当您在没有指定打印机的情况下在PrintDocument上调用print时,它当然会使用默认值:
PrintDocument doc = new PrintDocument();
doc.Print(); // will print a blank page
