到打印机和传真文件夹-->右键-->服务器属性

添加了自己定义的纸类型 名称949W300H 宽9.49in,高3.00in

所以改了程序为

foreach(PaperSize ps in printDoc.PrinterSettings.PaperSizes)

{

 if(ps.PaperName=="949W300H")

 {

  printDoc.PrinterSettings.DefaultPageSettings.PaperSize=ps;

  printDoc.DefaultPageSettings.PaperSize=ps;

 }

}

 

就可以了 似乎纸张只能从printDoc.PrinterSettings.PaperSizes中选择
