The way to do this would be to remove the NewDocument(3) call, which makes 3 identical documents, and restructure your code to something like this

Subroutine PrintInvoice(vHeader as String)

	//Code for NewPage and Variable declarations
	PrintString(vHeader, 100, 50, 0, "Arial", 16, 0)
	//Rest of your code here for printing an Invoice and FinishPage()

End Subroutine

PrintInvoice("Customer Copy")
PrintInvoice("Store Copy")
PrintInvoice("Delivery Copy")

In your case, you need to modify PrintHeader() to accept a string variable(which copy it is). Modify Line 25 and Line 37 to use that variable.

The code from line 277 to 332(and all required variables) need to go into the new Subroutine that I mentioned that accepts a string variable

Current Lines #'s 281 and 296 need to be modified to pass the argument passed to the new subroutine to the PrintHeader() subroutine.

Current line #'s 280, 333 need to be deleted

If you find yourself having an issue, I can make these changes for you, you'll just need to purchase some focused support time from https://www.lantica.com/shop/index.php/support/support-funit.html

Just 1 is enough.
