We'll now use the VBScript FileSystemObject object and the WSH network object. The network object would
Give us the methods we need to open a printer connection, and the FileSystemObject'll 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")
' Connect a network printer using WSH
Objwshnet.addprinterconnection "LPT1", Strprinterpath, False, strUserName, strpassword
' Use a file system object to use a print device as a file
Set objprinter = Objfs.createtextfile ("LPT1:", True)
' Send text to a print device
Objprinter.write (strmessage)
' Turn off print device objects and make error trap handling
On Error Resume Next
Objprinter.close
' If an error occurs, turn off the print connection and output the error message
If ERR Then
Response.Write ("Error #" & CStr (Err.Number) & "" & Err.Description)
Err.Clear
Else
' Operation succeeded, output confirmation information
