C#將縱向內容打印到橫向紙張上（打印旋轉）

遇到了一個打印問題，設計了一張標籤，要打印的內容是縱向的，要打印在 寬*高=8cm*10cm 的標籤紙上，結果在設計完後發現客戶購買的是 寬*高=10cm*8cm 的標籤紙，於是就嘗試使用 e.PageSettings.Landscape = true 來進行橫向打印，結果發現沒用的，內容還是從上到下打印的，而且最下面被截掉了。

print.DefaultPageSettings.PaperSize = new PaperSize("ERPPaper", 315, 394);
print.PrinterSettings.DefaultPageSettings.Landscape = false;              

 折騰了半天，最終發現用一下兩行代碼可以完美解決問題：

e.Graphics.TranslateTransform(0, 315);  
e.Graphics.RotateTransform(-90.0F);     

整體代碼如下： 

        private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
        {
            #region 80×100
           
            Font font15 = new System.Drawing.Font("黑體", 15F, System.Drawing.FontStyle.Regular);
            Font font18 = new System.Drawing.Font("宋體", 15F, System.Drawing.FontStyle.Regular);

            e.Graphics.TranslateTransform(0, 315);
            e.Graphics.RotateTransform(-90.0F);

            e.Graphics.DrawLine(Pens.Black, 5, 5, 311, 5); 
            e.Graphics.DrawLine(Pens.Black, 5, 5, 5, 390);
            e.Graphics.DrawLine(Pens.Black, 5, 390, 311, 390);
            e.Graphics.DrawLine(Pens.Black, 311, 390, 310 ,5);

            e.Graphics.DrawLine(Pens.Black, 62, 43, 155, 43);
            e.Graphics.DrawLine(Pens.Black, 62, 91, 155, 91);
            e.Graphics.DrawLine(Pens.Black, 62, 139, 288, 139);
            e.Graphics.DrawLine(Pens.Black, 62, 187, 155, 187);
            e.Graphics.DrawLine(Pens.Black, 62, 236, 155, 236);
            e.Graphics.DrawLine(Pens.Black, 75, 283, 155, 283);
            e.Graphics.DrawLine(Pens.Black, 62, 331, 288, 331);
            e.Graphics.DrawLine(Pens.Black, 100, 379, 288, 379);

            e.Graphics.DrawLine(Pens.Black, 211, 43, 300, 43);
            e.Graphics.DrawLine(Pens.Black, 211, 91, 300, 91);
            e.Graphics.DrawLine(Pens.Black, 211, 187, 300, 187);
            e.Graphics.DrawLine(Pens.Black, 211, 236, 300, 236);
            e.Graphics.DrawLine(Pens.Black, 211, 283, 300, 283);

            e.Graphics.DrawString("歸屬：", font15, Brushes.Black, 8, 21);
            e.Graphics.DrawString("品種：", font15, Brushes.Black, 8, 69);
