Adding auto-incrementing ref. to Word doc

Hi I'm not sure what technology would be used to do this - VBA? Please confirm. I would like to automatically insert an auto-incrementing reference code into a Word document before printing. So when I print multiple copies, each copy would have its own unique reference code. The format would be REF_CURRENTDATE_AUTONUMBER, e.g. REF_030805_001, REF_030805_002, REF_030805_003 and so on. The solution should work with 1 or multiple page Word docs.
