C# 利用PrintDocument定制打印單據

本文是利用PrintDocument定制打印單據的小例子，僅供學習分享使用，如果不足之處，還請指正。

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
PrinterSettings：設置打印機屬性，如：設置屬性Copies，可以設置打印份數，默認為1，
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：
