Try enumerating System.Drawing.Printing.PrinterSettings.InstalledPrinters.
尝试枚举System.Drawing.Printing.PrinterSettings.InstalledPrinters.
using System.Drawing.Printing;
string GetDefaultPrinter()
{
PrinterSettings settings = new PrinterSettings();
foreach (string printer in PrinterSettings.InstalledPrinters)
{
settings.PrinterName = printer;
if (settings.IsDefaultPrinter)
return printer;
}
return string.Empty;
}

if (GetDefaultPrinter(dp, ref size)) {
Console.WriteLine(String.Format("Printer: {0}, name length {1}", dp.ToString().Trim(), size));
} else {
int rc = GetLastError();
Console.WriteLine(String.Format("Failed. Size: {0}, error: {1:X}", size, rc));
