In the Sales Invoice, Sales Order ID is updated in the Sales Invoice Item table. For the quick solution, you can make this field/column visible in the Print Format.
Easy way you add new field sales_order (link to Sales Order) in Sales Invoice Form => When you create IV from SO => This field will update and can get this field to print.
