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> </HTML>
