如何在WPF中沒有打印對話框的情況下直接打印？

Question

我只想知道如何在不顯示WPF中的打印對話框的情況下打印流文檔。

感謝您的幫助......

Answer 1

您可以使用PrintDialog類類，而不顯示對話框（不調用的ShowModal）

Answer 2

嘗試

PrintDialog dialog = new PrintDialog(); 
dialog.PrintVisual(_PrintCanvas, "My Canvas"); 

Answer 3

這是可以改變的途徑之一默認打印機或更改其他設置：

using System.Printing; //add reference to System.Printing Assembly 
         //if you want to modify PrintTicket, also add 
         //reference to ReachFramework.dll (part of .net install) 
... 

var dlg = new PrintDialog(); 

dlg.PrintQueue = printer; // this will be your printer. any of these: new PrintServer().GetPrintQueues() 
dlg.PrintTicket.CopyCount = 3; // number of copies 
dlg.PrintTicket.PageOrientation = PageOrientation.Landscape; 

dlg.PrintVisual(canvas);
