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="ASPPrint.asp" method=POST id=form name=form>
<TABLE WIDTH=100% ALIGN=center BORDER=0 CELLSPACING=1 CELLPADDING=1>
<TR>
<TD ALIGN=right NOWRAP>网络打印机路径:</TD>
<TD ALIGN=left NOWRAP><INPUT type="text" id=printerpath name=printerpath
value="\\< Domain >\< Printer >"></TD>
</TR>
<TR>
<TD ALIGN=right NOWRAP>登录帐号:</TD>
<TD ALIGN=left NOWRAP><INPUT type="text" id=username name=username
value="<% = strUsername %>"></TD>
</TR>
<TR>
<TD ALIGN=right NOWRAP>登录口令:</TD>
<TD ALIGN=left NOWRAP><INPUT type="password" id=password
name=password></TD>
</TR>
<TR>
<TD ALIGN=right NOWRAP>请输入你想打印的文字:</TD>
<TD ALIGN=left NOWRAP><TEXTAREA rows=2 cols=20 id=message
name=message></TEXTAREA></TD>
</TR>
<TR>
<TD ALIGN=right NOWRAP> </TD>
<TD ALIGN=left NOWRAP><INPUT type="submit" value="Submit"
id=submit name=submit></TD>
</TR>
</TABLE>
</FORM>

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 = Request.Form("printerpath")
strUsername = Request.Form("username")
strPassword = Request.Form("password")
strMessage = Request.Form("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("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>")
Response.Write("<TABLE WIDTH=100% ALIGN=center BORDER=0 CELLSPACING=1 CELLPADDING=1>")
Response.Write("<TR><TD ALIGN=RIGHT><B>打印消息送出:</B></TD>")
Response.Write("<TD ALIGN=LEFT>" & strMessage & "</TD></TR>")
Response.Write("<TR><TD ALIGN=RIGHT><B>网络打印机路径:</B></TD>")
Response.Write("<TD ALIGN=LEFT>" & strPrinterPath & "</TD></TR>")
Response.Write("<TR><TD ALIGN=RIGHT><B>登录帐号:</B></TD>")
Response.Write("<TD ALIGN=LEFT>" & strUsername & "</TD></TR>")
Response.Write("</TABLE>")
Response.Write("</CENTER>")
End If
' 取消打印连接
objWSHNet.RemovePrinterConnection "LPT1:"
Set objWSHNet = Nothing
Set objFS = Nothing
Set objPrinter = Nothing
End If
%>
</BODY>
