Question

  private void Form2_Load(object sender, EventArgs e)
        {
            System.Drawing.Printing.PrintDocument _Documnet = new System.Drawing.Printing.PrintDocument();
            _Documnet.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(_Documnet_PrintPage);
            _Documnet.Print();
        }        void _Documnet_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            e.Graphics.DrawString(textBox1.Text, textBox1.Font, new SolidBrush(textBox1.ForeColor), 100, 100);
            
        }这样 100,100 你想定义到那都行

Answer 2

打印一张图下面少了句代码
Image temp = Image.FromFile(@"D:\网络.png");绝对路径，自己可以改

Answer 3

如果图片是picturebox里的 写字就直接drawstring就好了 没那么复杂
