水晶報表實現(xiàn)套打

對于套打的情況，一般出現(xiàn)在以下兩種情況：1：清單類打印，一般可能是已經(jīng)是在已經(jīng)印刷好的紙張上打印2：單據(jù)發(fā)票類，一般單據(jù)格式固定，如每張打印5行數(shù)據(jù)，而且這種格式是已經(jīng)印刷好的，當然機打發(fā)票除外。我們以第2種情況為例進行說明，因為第2種會了第1種也自然就明白了在這里我們使用程序代碼+報表中設置背景圖片的方式來實現(xiàn)。

1、紙張尺寸類型很難控制客戶端的，那就用A4紙，計算設置較大右邊距和下邊距，以適合你的單據(jù)尺寸；

2、頁面設置，精確計算左邊距與上邊距，放好你需打印的組件與不需打印的組件(Top與Left)；

3、窗體上，三個控件：CrystalReport控件、CrystalReportViewer控件和PRintDialog控件，讓CrystalReportViewer控件的ShowPrintButton=false，以免客戶從它啟動打印；

4、在制作報表的時候，把你不需要打印的部分使用圖片代替。

如下圖。

使用了圖片來代替固定數(shù)據(jù)。如上圖中的“倉儲企業(yè)名稱”等標題。

5、報表打印類：

7、套打，只打印數(shù)據(jù)的效果。如下圖。

8、非套打，全部打印的效果。如下圖。
