}

到打印機和傳真文件夾-->右鍵-->服務器屬性
添加了自己定義的紙類型 名稱949W300H 寬9.49in,高3.00in

所以改了程序為

foreach(PaperSize ps in printDoc.PrinterSettings.PaperSizes)
{
 if(ps.PaperName=="949W300H")
 {
  printDoc.PrinterSettings.DefaultPageSettings.PaperSize=ps;
  printDoc.DefaultPageSettings.PaperSize=ps;
 }
}

 

就可以了 似乎紙張只能從printDoc.PrinterSettings.PaperSizes中選擇
