注意的是：
由于这是演示，其中有关NT的帐号和密码都是使用了不加密的手段在ASP中传递的
真正的运用中应该对该登录过程进行安全处理。

We will now use the VBScript FileSystemObject object and the WSH Network object. The Network object will
give us the methods we need to open a printer connection, and the FileSystemObject will allow us to stream our
output to the printer. We create these objects in the following code example:
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objWSHNet = CreateObject("WScript.Network")
' 使用WSH连接网络打印机
objWSHNet.AddPrinterConnection "LPT1", strPrinterPath, False, strUsername, strPassword
' 使用文件系统对象将打印设备作为一个文件使用
Set objPrinter = objFS.CreateTextFile("LPT1:", True)
' 给打印设备送出文本
objPrinter.Write(strMessage)
'关闭打印设备对象并进行错误陷阱处理
On Error Resume Next
objPrinter.Close
' 如果发生错误，关闭打印连接，并输出错误信息
If Err Then
Response.Write ("Error # " & CStr(Err.Number) & " " & Err.Description)
Err.Clear
Else
' 操作成功，输出确认信息
Response.Write("<CENTER>")
