as many people i encoutered the fact that the activeport of the modi-printer keeps changing. Out there you find some solutions but my lack of programming knowledge prohibits me from getting it working correctly.

i want to print to tif file where the filename is in a cel And that it works regardless of the NE-port number.
so it should print to the MODI-printer and find out on what port it is and print/save the file as.......

Attached you find an example file i got it from an ealier post and hope someone can help me get it working. Below some examples of solutions that give an idea of what's the problem:

Try this:
Sub export()
   Dim strPrinter As String
   strPrinter = "Microsoft Office Document Image Writer"
    Sheets("boorgat coordinaten").Select
    Range("A1:P58").Select
    Path = "f:\klant_tekening\"
    Filename = Range("h4").Value & "." & Range("I4").Value & ".1" & ".tif"
    ActiveWorkbook.PrintOut 1, 1, 1, False, strPrinter & " op " & GetPrinterPort(strPrinter), True, False, Path & Filename, False
 
End Sub
Public Function GetPrinterPort(strPrinterName As String) As String
    Dim objReg As Object, strRegVal As String, strValue As String
    Const HKEY_CURRENT_USER = &H80000001
    Set objReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\default:StdRegProv")
    strRegVal = "Software\Microsoft\Windows NT\CurrentVersion\PrinterPorts\"
    objReg.getstringvalue HKEY_CURRENT_USER, strRegVal, strPrinterName, strValue
    GetPrinterPort = Mid$(strValue, 10, 5)
End Function

you could use the code from http://www.tek-tips.com/viewthread.cfm?qid=628174&page=8 to find out which printers are installed on your system.
It takes some tweaking to get it in a format you'd be looking for but it works.
In short, the upper function looks in the registry which NE port is linked to a specific printer name. The second function queries the registry for all known printer names and uses the getnewprinter function to combine these values.
As a proof of concept, the active printer is set and printed to the debug output for each printer.

succes !

Function GetNewPrinter(Printer As String) As String
'
' Get EXCEL printer name from windows printer name
' Input: printer name like "HP Laserjet"
' Output: printer name like "HP Laserjet at Ne02:"
'
Dim ws As Object
On Error GoTo ErrHandler

Set ws = CreateObject("WScript.Shell")
np = ws.regread("HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Devices\" & Printer)
If Len(np) >= 5 Then GetNewPrinter = Printer & " op " & Right(np, 5) Else GetNewPrinter = ""
Exit Function

ErrHandler:
GetNewPrinter = ""
End Function


Public Function ListAllPrinters() As String

   Dim lObj_ScriptControl        As IWshNetwork_Class
   Dim lCol_Printers             As IWshCollection_Class
   Dim lStr_PrinterList          As String
   Dim lInt_Idx                  As Integer
   
   Set lObj_ScriptControl = New IWshNetwork_Class
   Set lCol_Printers = lObj_ScriptControl.EnumPrinterConnections

   lStr_PrinterList = vbNullString
   For lInt_Idx = 1 To lCol_Printers.Count - 1 Step 2
      
      Debug.Print "Voor : " & Application.ActivePrinter
      new_printer = GetNewPrinter(lCol_Printers.Item(lInt_Idx))
      Application.ActivePrinter = new_printer
      Debug.Print "Na   : " & Application.ActivePrinter
      
      lStr_PrinterList = lStr_PrinterList & lCol_Printers.Item(lInt_Idx) & ";"
   Next lInt_Idx

   If (Right(lStr_PrinterList, 1) = ";") Then
      lStr_PrinterList = Left(lStr_PrinterList, Len(lStr_PrinterList) - 1)
   End If

   Set lObj_ScriptControl = Nothing
   Set lCol_Printers = Nothing
   
   ListAllPrinters = lStr_PrinterList

End Function

For the code to run, you have to add a reference to the "Windows Script Host Object Model"
