c# 获取默认打印机配置文件并保存配置文件到D盘中，加载取默认打印机配置文件

获取默认打印机配置文件并保存到D盘中的代码示例：

using System.Drawing.Printing;
using System.Runtime.InteropServices;

[DllImport("winspool.drv", CharSet = CharSet.Auto, SetLastError = true)]
private static extern bool GetDefaultPrinter(StringBuilder pszBuffer, ref int size);

public void SaveDefaultPrinterSettings()
{
    // 获取默认打印机名称
    var sbPrinterName = new StringBuilder(256);
    int size = sbPrinterName.Capacity;
    if (GetDefaultPrinter(sbPrinterName, ref size))
    {
        // 获取打印机配置信息
        var printerSettings = new PrinterSettings();
        printerSettings.PrinterName = sbPrinterName.ToString();

        // 保存到D盘
        printerSettings.Save(@"D:\defaultprinter.settings");
    }
}

加载默认打印机配置文件并应用的代码示例：

public void LoadDefaultPrinterSettings()
{
    var printerSettings = new PrinterSettings();
    printerSettings.Load(@"D:\defaultprinter.settings");

    // 应用配置
    printerSettings.PrinterName = printerSettings.PrinterName;
    printerSettings.Copies = printerSettings.Copies;
    // ...
}
