嵌入字体的Winform.net PrintDocument抽绳无效

在谷歌进行了多次搜索之后，我来到这里寻求帮助： 问题：当我尝试使用printDocument绘制时，代码显示默认字体（Arial）。 请帮忙

删除这个

System.Runtime.InteropServices.Marshal.FreeCoTaskMem（fontPtr）并在
Form1.Closed
事件中处理
fonts
（PrivateFontCollection对象）和
mySignatureFont
。看起来您正在使用PrintPreviewControl。使用其Paint事件使用该字体绘制字符串，而不是PrintDocument.PrintPage事件。顺便说一句，请阅读此处的注释：如果您想从文件（在任何情况下都是字节数组）加载字体，请选择您喜欢的代码版本。
namespace EmbededFonts
{
    public partial class Form1 : Form
    {

        [System.Runtime.InteropServices.DllImport("gdi32.dll")]
        private static extern IntPtr AddFontMemResourceEx(IntPtr pbFont, uint cbFont,
            IntPtr pdv, [System.Runtime.InteropServices.In] ref uint pcFonts);

        private PrivateFontCollection fonts = new PrivateFontCollection();

        Font mySignatureFont;

        public Form1()
        {
            InitializeComponent();

            byte[] fontData = Properties.Resources.SignatureFont;
            IntPtr fontPtr = System.Runtime.InteropServices.Marshal.AllocCoTaskMem(fontData.Length);
            System.Runtime.InteropServices.Marshal.Copy(fontData, 0, fontPtr, fontData.Length);
            uint dummy = 0;
            fonts.AddMemoryFont(fontPtr, Properties.Resources.SignatureFont.Length);
            AddFontMemResourceEx(fontPtr, (uint)Properties.Resources.SignatureFont.Length, IntPtr.Zero, ref dummy);
            System.Runtime.InteropServices.Marshal.FreeCoTaskMem(fontPtr);

            mySignatureFont = new Font(fonts.Families[0], 16.0F);

        } 

        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            e.Graphics.DrawString("My Artistic Signature", mySignatureFont, Brushes.Black, 10, 10);
        }

        private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            e.Graphics.DrawString("My Artistic Signature", mySignatureFont, Brushes.Black, 10, 10);
        }
    }
}
