 代码没问题的。你掉出任务管理器，把所有的excel进程都结束后，再测试下面代码

 

Dim pnt As WinForm.ComboBox = e.Form.Controls("printer")\'取得打印机名称
Dim pntn As String = pnt.Text
SaveConfigValue("pntname1",pntn)
Dim Book As New XLS.Book(ProjectPath & "Attachments\\电汇.xls")
Dim fl As String = ProjectPath & "Reports\\电汇.xls"
Book.Build() \'生成细节区
Book.Save(fl) \'保存工作簿
Dim App As New MSExcel.Application
try
    Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open(fl)
    Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
    Ws.PrintOut(ActivePrinter:=pntn)
catch ex As exception
    msgbox(ex.message)
finally
    App.quit
End try
