本文是利用PrintDocument定制打印單據的小例子。
涉及知識點：
- PrintDocument :從 Windows 窗體應用程序打印時，定義一種可重用的可發送到打印機上的對象。
- PrintPreviewControl :表示 Windows 窗體應用程序打印預覽的原始預覽部分，沒有任何對話框或按鈕。
- Graphics ：GDI+繪圖對象
- PageSettings：指定應用於單頁打印的設置
- DefaultPageSettings：PrintDocument的屬性
- PrintPage事件：PrintDocument的事件，通過此事件來繪制需要打印的內容
- PaperSize：指定紙張大小
- 毫米和英寸的換算：打印機是以英寸為單位的，單據設置是以毫米為單位的，所以需要轉換
效果圖如下：
關鍵代碼如下：
