Limiting Printing to a Workbook from a Set Location

Stefano is having a problem in his company where people will often copy a workbook from the server to their own computer, make changes in the workbook, and then print the workbook. He would like to enforce that only the original workbook is allowed to be printed, so he wonders if there is a way to prohibit printing unless the workbook is the one on the server.

There is no native way to do this in Word. You could, if desired, create a macro that did the following two things:

1. Examine the path for the current document
2. If the path is anything except the path for your server, prohibit printing

Here's an example of such a macro. You should place this particular version in the ThisWorkbook module; it automatically runs every time the user chooses to print.

Private Sub Workbook_BeforePrint(Cancel As Boolean)
    Dim sFile As String

    sFile = "\\Server.name\folder\path\My file name.xlsm"

    If ThisWorkbook.FullName <>  sFile Then
        MsgBox "Printing only possible with server copy"
        Cancel = True
    End If
End Sub

Note that the sFile variable is set to contain the full path to the workbook (to where the workbook should be located on the company server). If the name of the current workbook doesn't match this, then printing is disabled.

There is a potential problem with this type of macro, and it has to do with the path to the file. It is possible that the path for the server may differ on a user-by-user basis. The example macro checks for a path that includes a UNC (Universal Naming Convention), but not all paths might work this way. For instance, users might have the folder on the server mapped to a drive letter. On one system the path might be g:/myserver/myfolder/ and on another it might be z:/myserver/myfolder/. The macro cannot reliably compensate for this.

You might be able to get around this with a definitely low-tech approach. First, put a small text file (created with Notepad) into the same folder on the server as the workbook. It isn't really important what the text file contains. Then, add this macro to your ThisWorkbook module:

Private Sub Workbook_BeforePrint(Cancel As Boolean)
    Dim sPath As String
    Dim sFile As String

    sPath = ThisWorkbook.Path
    sFile = sPath & "\" & "TestFile.txt"

    If Dir(sFile) = "" Then
        MsgBox "Printing only possible with server copy"
        Cancel = True
    End If
End Sub

What the macro does is to determine the path of the currently open workbook. This is then added to the name of the small text file you placed in the same folder as the workbook. (In this case, I've given this file the name TestFile.txt.) The Dir command is then used to see if the file exists. If it doesn't exist, then the printing is cancelled.

A more encompassing solution might be to use what Microsoft refers to as IRM (Information Rights Management). This solution, which is well suited for use in a corporate environment, allows you to control what people can and cannot do with your documents. A good place to start learning about IRM is here:
