I have a question:

I make a sales order , the I make a delivery after I make a invoice
On the invoice line (nr 8 en 9) I see some information about the delivery note etc.
but this information is not printed

Only what is printed is the charge or the product on the invoiceline,
How can I make it possible that it also shows the delivery information on the invoice?
