主题：打印

各位师傅好：

按照范例打印代码

If Functions.Execute("net20sp1") = False Then
    Return
End If
Dim Book As New XLS.Book(ProjectPath & "Attachments\统计表.xls")
Dim fl As String = ProjectPath & "Reports\统计表.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

红色部位如何改，请师傅指点，谢谢！
