c# 使用打印机打印并设置打印位置及宽高

1.在界面中使用自带的控件printDocument

2.将以下函数绑定到控件的PrintPage事件

  private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            try
            {
                if (CurrtPrintImage != null)//此处是打印一个图像，CurrtPrintImage是Image类型
                {
                    float x;
                    float y;
                    float width;
                    float height;
                    switch (comboBox1.Text)//此处此页共可打印多少个图像
                    {
                        case "8"://总个数为8
                            string location = comboBox2.Text;//此处是将当前图像打印到此页的哪个位置。
                            if (Convert.ToInt32(location) % 2 != 0) //奇数1，3，5，7
                            {
                                x = printDocument1.DefaultPageSettings.PaperSize.Width / 4.0f - printDocument1.DefaultPageSettings.PaperSize.Height / 8 + 20;
                                y = (printDocument1.DefaultPageSettings.PaperSize.Height / 4.0f) * (Convert.ToInt32(location) / 2);
                            }
                            else //偶数2，4，6，8
                            {
