如何使用PrintDocument类打印WEB页面？

[MAX°孟兆]

现在我在WEB中有一个DataGrid1，显示一个表的数据，
现在我用PrintDocument进行打印，可是为什么打印出来是一片空白？

Imports System.Drawing.Printing
Imports System.Data
Imports System.Data.SqlClient

Public Class print

Protected pd As PrintDocument

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'在此处放置初始化页的用户代码
Dim conn As New SqlConnection("server=ZMZ;database=pubs;user id=sa;password=;")
Dim comm As New SqlCommand("SELECT * FROM authors", conn)

conn.Open()

DataGrid1.DataBind()
Dim dr As SqlDataReader = comm.ExecuteReader()

DataGrid1.DataSource = dr
DataGrid1.DataBind()

conn.Close()

pd = New PrintDocument()

' 枚举系统已安装的打印机
If Not Page.IsPostBack Then
Dim pkInstalledPrinters As String
For Each pkInstalledPrinters In PrinterSettings.InstalledPrinters
PrinterList.Items.Add(pkInstalledPrinters)
Next
End If
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
pd.Print()
End Sub

Private Sub PrinterList_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrinterList.SelectedIndexChanged
If PrinterList.SelectedIndex <> -1 Then
' The combo box's Text property returns the selected item's text, which is the printer name.
pd.PrinterSettings.PrinterName = PrinterList.Items(PrinterList.SelectedIndex).Text
End If
End Sub

请高手指点！！！

是服务器端代码，没法实现客户端的打印，你可以调用IE的PRINT方法。

To x1_x11(x1_x11=??)
那要实现像我上面情况的打印除了用IE的PRINT方法外还有什么方法呢？

好象没有了，:(，有一个办法：把要把打印的内容写成一幅JPG的图片在IE中显示出来，这样就好控制IE的打印了

to:x1_x11(x1_x11=??) 怎么写成一幅图片???

用脚本吧

对于连打各位有什么想法，就是让打印机自动打印一批URL中的网页？
