Woudl it be possible to write the whole Macro with that functionality
in it please? I have tried this:

Sub ExportToPRN()
Dim FName As String
Dim WholeLine As String
Dim FNum As Integer
Dim myRange As Range
Dim myCell As Range
Dim myName As String
Dim Cell As Range
Dim OutputDir As String

myName = ActiveWorkbook.FullName

FName = Application.GetSaveAsFilename( _
Replace(myName, ".xls", ".prn"))

On Error GoTo EndMacro:
FNum = FreeFile

Open FName For Output Access Write As #FNum
Set myRange = Range("C1:C2")
WholeLine = ""

For Each myCell In myRange

WholeLine = WholeLine & "\" & myCell.Text & vbNewLine
MkDir OutputDir & Cell.Value

Next myCell

WholeLine = Left(WholeLine, Len(WholeLine) - 1)

Print #FNum, Trim(WholeLine)

EndMacro:
On Error GoTo 0
Close #FNum
End Sub

But have had no success. What am I doing wrong?
