There are several different options but the easiest to work with would most likely be to set it up as INI type file and use the READPROFILESTRING()
1. Set it up like an INI
[Section]
old=new
old2=new2

 Code:
For each $Printer in $PrinterArray
  $NewPrinter = ReadProfileString(@ScriptDir+"\Printers.INI","Section",$Printer)
  DelPrinterConnection($Printer)
  AddPrinterConnection($NewPrinter)
Next


Obviously this is only an example and will take some flushing out but should give you the idea of how to start.
