Auto print copy number

Question

Using Adobe 8 Professional
I have a 40 page document in which I will need to print 300 (+/-) copies of.  I want to print an incremental 3 digit "form" number on the first page of each copy so that my first set prints "100", the second set "101", etc.  It would be ideal if the form number could repeat once it gets to number 104, but I would settle for running numbers.
Is there a way to do this and if so, how?

Answer 1

You will need to add a form field to the first page. You can then use JavaScript to create a controlled loop action to add 1 to the value of the form field and print print that copy, and then repeat that loop until 300 copies are printed.
Assuming you have a field named "Copy_Number" on page 1 of the PDF.
// print 300 copies:
for(i = 0; i < 300; i++) {
this.getField("Copy_Number").value = i + 1; // add copy number to PDF
this.print(); // print the PDF
} // end loop
