You can a print delivery note one of two ways either.
1.Go to the sales section >customers and put a tick in the box to the left of the date and hen go to batch actions and then print delivery note
2.go to sales>all sales>filter drop down>change type to invoices>change customer to specific one or leave at all depending on how many you need>change date range if you need>then you can tick to the left of the date a>go to batch actions>print delivery note
The first option is best if you need to do one on a specific customer the other option you can use if need to do for multiple.
