  您需要使用DrawString的重载，它允许您在给定矩形内布局文本 . 要确定矩形的大小，请使用MeasureString . 跟踪额外变量中的垂直位置 . 你的代码看起来像这样：

  private int DrawWrapped(string text, Font f, Point location, Size maxSize, Graphics g)
  {
      // how much space is needed
      var neededRect = g.MeasureString(text, f, maxSize.Width - location.X);
      var rect = new Rectangle(location, neededRect.ToSize());
      g.DrawString(text, f, Brushes.Black, rect, StringFormat.GenericDefault);
      return (int) Math.Ceiling(neededRect.Height);
  }
  
  private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
  {
      int y = 373; // keep track of where we are on the page vertically
      using (var arial14 = new Font("Arial", 14, FontStyle.Regular))
      {
          // add the used height to where we are
          y += DrawWrapped("DEVICE INFORMATION:", arial14, new Point(286, y), e.PageBounds.Size, e.Graphics);
          y += (2 * arial14.Height); // add some white space
      }
      using (var arial15 = new Font("Arial", 15, FontStyle.Regular))
      {
          y += DrawWrapped("Device Type:" + devices.Text, arial15, new Point(50, y), e.PageBounds.Size, e.Graphics);
  
          if (devices.Visible == true && devices.Text == "Console") // better use && me thinks 
          {
              y += DrawWrapped("Type of Console:" + consoleTextBox.Text, arial15, new Point(50, y ), e.PageBounds.Size, e.Graphics);
          }
          if (comboBox3.Visible == true) //iphone selection box is visible then show selected model on print document
          {
              y += DrawWrapped("Type of Phone:" + comboBox3.Text, arial15, new Point(50, y ), e.PageBounds.Size, e.Graphics);
              y += DrawWrapped("Service Type:" + serviceDesc.Text, arial15,  new Point(50, y ), e.PageBounds.Size, e.Graphics);
              y += DrawWrapped("Description:" + description4Repair.Text, arial15, new Point(50, y), e.PageBounds.Size, e.Graphics);
          }
      }
  }
  

  这就是结果：
