I'll guide you with this, Purruno.
Depending on the region or how it is called, you can print a delivery note (packing slip) when you click on Print or Preview on the Invoice page.
For batch printing:
- From the left menu, select Sales then choose Customers.
- Select the customer's name to display a list of their transactions.
- From the Transaction List tab, select the box next to each invoice or sales receipt for which you want to print a Packing Slip.
- Select the Batch actions drop-down, then choose Print packing slip.
- The print preview screen will open so you can select printing options, preview, and print.
Let me know if you have other questions in mind. Have a good one!
