C# 利用PrintDocument定製列印單據

本文是利用PrintDocument定製列印單據的小例子。

涉及知識點：

• PrintDocument :從 Windows 窗體應用程式列印時，定義一種可重用的可發送到印表機上的對象。
• PrintPreviewControl :表示 Windows 窗體應用程式列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：指定應用於單頁列印的設置
• DefaultPageSettings：PrintDocument的屬性
• PrintPage事件：PrintDocument的事件，通過此事件來繪製需要列印的內容
• PaperSize：指定紙張大小
• 毫米和英寸的換算：印表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：
