主题：报表打印代码

师傅你好：

在帮助文件中有下列打印按钮代码，不知("net20sp1") 代码代表什么，在实际使用中如何设置，谢谢！

If Functions.Execute("net20sp1") = False Then
    Return
End If
Dim Book As New XLS.Book(ProjectPath & "Attachments\资料卡.xls")
Dim fl As String = ProjectPath & "Reports\资料卡.xls"
Book.Build()
Book.Save(fl)
Dim App As New MSExcel.Application
Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open(fl)
Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
Ws.PrintOut
App.Quit
