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
<FORM action="ASPPrintasp" method=POST id=form name=form>
<TABLE WIDTH=% ALIGN=center BORDER= CELLSPACING= CELLPADDING=>
<TR>

当以上信息被提交后就可以按照下面的代码进行打印了

从form中取得响应信息
strPrinterPath = RequestForm("printerpath")
strUsername = RequestForm("username")
strPassword = RequestForm("password")
strMessage = RequestForm("message")
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("ScriptingFileSystemObject")
Set objWSHNet = CreateObject("WScriptNetwork")
使用WSH连接网络打印机
objWSHNetAddPrinterConnection "LPT" 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 = objFSCreateTextFile("LPT:" True)
给打印设备送出文本
objPrinterWrite(strMessage)
关闭打印设备对象并进行错误陷阱处理
On Error Resume Next
objPrinterClose
如果发生错误关闭打印连接并输出错误信息
If Err Then
ResponseWrite ("Error # " & CStr(ErrNumber) & " " & ErrDescription)
ErrClear
Else
操作成功输出确认信息

取消打印连接
